Strange problem with UNIX machines [7:36993]
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 ?

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.

Re: Source Quench [7:12477]
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. Regds 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]
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 __ Do You Yahoo!?

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 ?

Re : ISDN Backup
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.

And to have a threshold level you need to use the command BACKUP DELAY, and for the threshold you need to use the command BACKUP LOAD which will be a percentage of the primary line's available bandwidth that the traffic load must exceed to enable dial backup. The best thing is to send the output of the Running congfig and we can take it from there as I think I am walking blindly into this.
