RE: best practice

2000-09-05 Thread Buddy Venne

JMcL -
I can think of a few that are standard here. These may be more basic than
you are asking for, but it's a start:

service timestamps debug datetime localtime show-timezone // who needs
milliseconds anyway??

service password-encryption
logging buffered 4096 debugging // keep the log locally
ip subnet-zero // a default I think
clock timezone PST -8 // ymmv
clock summer-time PDT recurring // ymmv

On each interface:
  no ip directed-broadcast

On a Frame Relay interface, I put the port speed as the bandwidth, and the
sub-interfaces get their respective PVC CIR as the bandwidth. eigrp
calculations use the subs, and the other is there for documentation only.
(Although I think Concord uses it for graphs.)

In the router eigrp section
  eigrp log-neighbor-changes

ip classless // defaults
ip http server // defaults

logging trap debugging // lots of detail
logging source-interface Loopback0 // all log messages sourced from lo0

logging 10.2.1.20 // our syslog server
snmp-server chassis-id JAB0332A3Q5  // so I have the serial number
documented

banner exec ^C// so I "remember" the model  version as I log in

Model 2610, Version 12.0(3c)
^C

ntp server 10.252.1.1 prefer  // centralized time server

I hope this is a start. I welcome any feedback. bv

Subject: best practice




This question is sort of off topic (and very broad) but it could start up
all
sorts of interesting on-topic threads so I'll ask it anyway.  And anyway,
groupstudy's quiet - does the US have a holiday yesterday or something
(timezones do funny things to sentences :-)?

I'm doing a clean up and general revision of some of our router configs -
removing stuff that is no longer needed, changing parameters that are no
longer
appropriate, etc etc.

What commands/configurations are viewed as current general 'best practice'?
I'm
thinking of things like 'no ip directed-broadcast', 'ip classless' and 'no
service blah blah', that have become defaults in later IOS versions, and
also
more specific stuff like when to use which form of route caching, or
guidelines
from presentations/remote corners of CCO (e.g. I've got some configuration
guidelines for configuring frame relay traffic shaping which come from a
Networker's presentation - I've posted them before but let me know if anyone
wants them posted again).

I know the ultimate answer will be 'it depends' (after all, if there was a
single 'best way' the parameters wouldn't have to be user-configurable) -
I'm
more looking for things to consider.

To restrict it a bit, some of the things I am running on the routers
include...
IOS 11.2
frame relay (using sub-interfaces and frame relay traffic shaping)
ISDN (natively and using an external TA)
IPX (with IPX RIP)
IP (with OSPF and statics)
prioritisation
access lists for filtering and prioritisation
SNMP/RMON
NTP
HSRP

Thanks,
JMcL

RE: Can't connect to a Cisco/Grand Junction 2800 Switch via serial

2000-08-31 Thread Buddy Venne

Group -
At last a question I can answer!
You can 1.) Build a custom db9 adapter that raises CD toward the 2800 and
does the null-modem functions, or 2.) force an arp entry into a router on
the same Ethernet segment.
To get access I used method #2 which is described in the attached text file.
Later I built the adapter which I still have. If you need the pin out:
rj45 - db9
18
21,6
32
45
55
63
74
87
happy hacking

Subject: Can't connect to a Cisco/Grand Junction 2800 Switch via serial


I have tried several serial cables. I can connect to other cisco equipment
fine. My terminal program says it is connected but no response from key
strokes. I move the cable to a router and hit enter and I get a login. I
move it back to the switch and nada Any ideas. I did try a null modem
cable and at least got one wierd ATxxx thingy in the screen. When I go back
to a standard serial cable - nothing. I would love any advice.

Journal entry October 9, 1999:

The problem:
Catalyst 2800 and we can't access the cli.
We don't know the MAC, or the ip it used to have.
Console port communicates but does not seem to be of use. It sends AT command strings 
which would be to configure a modem if one was on there. no menu prompts. 

I got on to the 1605 that is on the same ethernet segment as one of the switch ports. 
I tried a ping 255.255.255.255 and then look at the arp table, but no luck
I tried to get the serial port running, but no luck I got 2 modems back to back, a 
sportster on the switch and a courier on the attacker
I used c0 to tell the modem to ignore CD, and d0 to ignore DTR, that way I can plug 
and unpluig
I used one terminal and ste it all up. I kept moving the terminal from the sportster 
to the courier I set the courier to go into "Originate mode from the front switch. I 
plugged into the sport and issued ata to start answering
I plugged the sport to the switch and then put the terminal cable in the courier, and 
as I was doing that I pressed the front switch and it went into training.
this was all for nought, because the serial port was not responding to my a enter, b 
enter, c enter, d. . . . on through h or so. I did not get as far as M, which may have 
been the one that would have worked.

but anyway at labb I got into config t mode and tried to add an arp entry with arp 
2.2.2.2 00c0.id80.29ac arpa ethernet 0
adn the same alias at the end
no luck because the router said invalid arp command, must be bridging. I tried several 
modes of bridge group 1
which enables it and then go to the interface and issue ip bridge-group 1 and other 
commands, but these did not work.

I then thought, why not add an address that would be valid if there was a lan on E0? 
so I gave it 219.17.100.5, and put that in an arp command. still error.
Then I went to global conmfig mode and issued ip host-routing and then tried to add 
the arp entry, and it worked.
then I pinged and it worked and then I did telnet and it worked. voila! menus and 
such. I could not find a place to set a fixed ip address. but in VLAN 1 we put 
219.17.100.5 255.255.255.0 and this may be where it is put in. It is not clear.

I felt good.

Sub-interface access-list question

2000-06-15 Thread Buddy Venne

All-
Can I apply an access list to a sub-interface? 
Background:
Generally a hub and spoke network. Company "A" at central site, company "X"
15 miles away.
Central site router is a 7204, need to have only company "X" network _not_
learn our routes, but still have 2 dynamic routes back to us. All other
remote sites can learn all routes.
The routing protocol is eigrp, and the two paths between company "X" and
central  are point-point T1 and Frame Relay. Remote router is a 3640. The
frame relay connection is multipoint frame relay on a subinterface here.
thanks
