Strange problem with UNIX machines [7:36993]

2002-03-01 Thread Amit Gupta

hello All,

I am facing a strange problem with one of our UNIX
Servers.
I am able to ping and telnet from this UNIX machine to
any other server/machine but it pings occasionally the
other way round.

I have checked the speed and duplex settings on the
Cisco Catalyst switch and matched it with this HP UX
Server 

I have also checked the Subnet Mask of the server.

Any Suggestions ?


Regards

Amit

Access list question [7:36166]

2002-02-21 Thread Amit Gupta

Hello All,


I want to set up an access list on the MSFC so that
traffic from a particular vlan or a range of IP
addresses is forwarded through another serial
interface.

My Ip range is x.x.x.240 - x.x.x.255 
We are using a Subnet Mask of /28

Any Clues ?


Thanks in Advance

Regards

Amit

making the router boot from an alternate location [7:31716]

2002-01-12 Thread Amit Gupta

Hello,

I have been booting my 3640 router through the tftp
server.
Recently I have installed a Flash Card and have loaded
the same IOS image in that too.

I want to configure my router to boot from the flash
card as the default option and in case of problems,
boot from the tftp server as a failsafe mechanism.

Please forward your comments.

Thanks  Regards

The local loopback/ hairpinning is working fine at one

I understand you to say that there are two 5505s on each

connects to a 6509.
Has anyone changed the config of any of the switches lately?
Any hardware

Do all the users on a floor who loose connectivity connect
to the same 5505?
Does the aggregate of all users on all floors who loose

to the 6509 through the same blade via their 5505s? Any
error messages on
the 6509? What's the uptime? What does a show log provide?
What is the bandwidth of the links between the 5505s and the
6509?
If gig, do you have any spare GBICs? I have heard reports of
failing units.
Any construction in the building? How about lots of dust in

Any commonality to the electrical feeds for the switches?

 I must admit this is my first question posted to the
group, 
 though I've been 
 a lurker for a long time.  Here it is:
 
 We have workstations on 10 different floors (each floor 
 divided in half, 
 each half a different subnet), all connected to 5505's (20
in 
 total).  From 
 the 5505's fiber goes to a 6509, then ultimately to the
WAN 
 via ATM.  The 
 servers all plug into the 6509.  So far, so good.
 
 For the past 3 days we have had workstations (not all, but

 about 50%)on 
 every floor lose connectivity to the network, whereby all
of 
 our NT and 
 NetWare servers are unavailable and web browsing is gone.

 This has happened 
 a total of 6 times, and there doesn't appear to be a
pattern 
 to the time or 
 network utilization.  Most times the users have to reboot,

 though sometimes 
 they can reconnect without a reboot.
 
 Can anyone help steer me in the right direction?  Our WAN 
 guys can't help, 
 and I have a feeling that it's going to be up to me to
figure 
 this one out.
 
 Thanks a lot.

Hello Stephen,

Thanks for your reply.

The Speed and the duplex settings of the server giving

The ping from any other Unix machine is Ok.

 The Source-Quench message comes from a server when

 this usually means that the nt is set for 100/Full -
 the switch is set for 
 100/full for the nt box , but the UX box (and its
 switch port)is only set 
 for 10/half ...usually the switch is aet to auto .
 
 without any special processing on the switch it will
 just send as many

 check the settings on both servers and make sure

Re: Source Quench [7:12477]

2001-07-17 Thread Amit Gupta

Hello Priscilla,

Thanks for your response.

Yes, it could not be a problem with the NIC since Ping
from any of the UNIX machines is fine.

I am using the default timeout while pinging from Unix
machines. I get a Source quench message even when I
specify a higher timeout  setting.

Amit

--- Priscilla Oppenheimer  wrote:
 I doubt it's related to a problem with the NIC. If
 there were a problem 
 with the NIC, it would probably be unable to respond
 at all or to send the 
 source quench.
 
 The server is just telling you that it doesn't have
 buffers or other 
 resources to handle the ping. When you ping from the
 Unix machine, what is 
 the timeout? Does the Unix machine send less often
 than the router, 
 resulting in the server not getting overwhelmed?
 
 What else is the server doing? I have seen Mac OS
 send source quench when 
 pinged. I have never considered it a problem. The
 Mac is OK in every other 
 respect.
 
 I'm glad this topic came up again because I had
 previously said that source 
 quench was obsolsete per RFC 1812. RFC 1812 is
 Requirements for IPv4 
 Routers. A router should not send a source quench.
 
 But a host may send a source quench. Per RFC 1122,
 Requirements for IP 
 Hosts, a host may send a source quench message if
 it is approaching, or 
 has reached, the point at which it is forced to
 discard incoming datagrams 
 due to a shortage of reassembly buffers or other
 resources.
 
 Even though RFC 1122 is old, it has not been
 replaced as far as I can tell. 
 So, source quench is not obsolete for hosts.

Help on VLAN configuration [7:8127]

2001-06-12 Thread Amit Gupta

Hi All,

The scenario is such that I have 2 subnets configured
on the LAN. They are x.x.1.0 / 24 and x.x.2.0 / 24.
The IP address for the Routers ethernet port are
x.x.1.1 and x.x.2.1. Similarly workstations in either
subnet point to these addresses ( x.x.1.1 and x.x.2.1
) as their default gateways.
I am having Cat 5509 and Cat 6609 ( With MSFC) with
all the ports in the default VLAN1

I have the following queries on this :
Config on MSFC

Can the IP addresses of the vlan interfaces be any one
of the free IP address available on the LAN.
For eg x.x.1.3 

What will be the default gateway address configured on
MSFC in this case ? ( Will it point towards the
address  of the Ethernet interface of the External
router )

On the Switches

Can both switches be configured in the VTP Server mode
?
Do the trunk ports have to have an IP address ?

DHCP Server

How would I have to define the scopes on the DHCP
server.
Suppose I plan to have 1 Vlan configured for 1 subnet
and 4 VLANs in the second subnet. How to go about it.

Thanks in advance for any kind of help/ suggestions

 With CBWFQ your voice
 traffic is going to be weighted based on class, just
 like other traffic, and
 even in a best case scenerio could still get some

 unpredicatable latency..or are you
 recommending CBWFQ solely

Voice Over IP

2000-12-27 Thread Amit Gupta

Hi everybody,

I need assistance on the VoIP problem I am facing :

We are planning to have a VoIP setup on the already
existing data link between our local and remote
office.
Both sites have Cisco 3640 routers configured for it.

The router on the local site has IOS 11.3(9)T and the
remote router has 12.0(5)T1 on it.

Is it necessary for the routers at both ends be
running a similar version of IOS for the Voice calls
to be successful. What kind of upgrade is required?

Secondly the loopback test (hairpinning) was
successful for the local site but a similar test at
the remote site was unsuccessful.
Could that be due to any signalling problems ?

Thanks  Regards

Re : ISDN Backup

2000-12-14 Thread Amit Gupta

Hi jenny,

Yes, I agree that with floating static routes backup
delay command would not work.
When my serial link is completely down then the ISDN
backup works perfectly well. It is only when the
serial link is flapping that the real problem comes up
as neither the condition of the link is good enough to
handle the load nor does it allow ISDN to takeover.

In such situations how can I prevent downtime by
allowing the ISDN to take the load.

Secondly I wanted to increase the ISDN bandwidth by
adding more ISDN lines.( The present bw is 128kbps
(multilink enabled)
Any hints/suggestions on that would also be
appreciated.

Thanks  Regards

Amit




 
You don't need to use the backup delay command if
you're using floating
static routes for backup, in fact I'm not sure that it
will actually do
anything (how does it know what the secondary
interface is without a backup
interface command?), but I've never actually tried
using it with floating
statics.
Using floating statics, how quickly the backup line
kicks in should depend
on the convergence time of your routing protocol and
design.  EIGRP should
be pretty quick, generally.
What puzzles me, though, is the statement 'isdn backup
is not able to
activate (momentarily activates and then
disconnects)'.  Do you mean that
the ISDN call doesn't work, or that the call is
disconnecting before the
idle timer expires or what?
Generally (depending on bits of the config that you
haven't shown), if the
serial link goes down for long enough for the routing
table to point to the
ISDN instead, the ISDN will call and will stay up for
at least 120 seconds
(default idle time), even if the routing quickly
reconverges back to the
serial.
If the serial link goes down (or has errors) for such
a short period that
the routing table does not point to the ISDN, then the
ISDN won't call at
all.

Does it work OK when the serial link goes down and
stays down?  If so, how
quickly does the ISDN activate?
If the serial link is flapping, is the ISDN call
(including PPP negotiation
if you're using PPP) successful?  debug isdn q931 and
debug ppp neg or
debug ppp auth may show any connection problems, and
debug dialer may show
why it is disconnecting.

You do not have to use the BACKUP INTERFACE command,
that is just another
way of doing
it.  I like the floating static commands much better,
I can test the ISDN
connectivity
without having to take the serial interface down.  And
the Backup Interface
command does
not work very well in a frame relay situation.

I do agree you need to add the commands for Backup
Delay, both for going to
ISDN and
going back to the primary.

As for preventing the WWW traffic when on ISDN, apply
an access list to the
BRI to
prevent it.

ip route 0.0.0.0 0.0.0.0 Serial0/0
ip route 0.0.0.0 0.0.0.0 bri1/0 150 

I am using ISDN as the backup interface.
The problem is that when my Serial link is erratic
(not down), isdn backup is not able to activate
(momentarily activates and then disconnects)
what feature should I use to activate my backup
immediately as soon as it senses a break in the serial
link.
Can I set some threshold level?

Secondly I wanted to stop the www traffic when my ISDN
backup is up ??
Any suggestions.

Thanks  Regards

Amit

The network would be considered unhealthy if it is experiencing more than
.1% of packets colliding (do the math). As for your question regarding
what does it take to shut a port down (errDisable) take a look at this

urgent 6509 msfc down.

2000-08-18 Thread Amit Lilani

hi guys,

i have a 6509 switch with 2 sup 1's and 2 msfc's ( modules 15 and 16)
what went wrong was we upgraded the msfc module with the wrong ios code
(12.07.XE1). no it does not seem to come up and goes into a loop. still i
can go into RMON using the switch console command. put whenever i use xmodem
to upgrade the ios it FAILS... its gives the message timeout and say
automatic logout... i spoke to cisco tac... (very slow in responding back)
they mailed me back saying the baud rate can not go more that 9600 on a
console which is true..I DONT know how to proceeds ...any
clues...suggestions are most welcome

thanks a lot for all your help

amit.
