Re: DHCP Relay Bug?

Thanks Cenk. I realised this recently but I'm not unsure of the impact were we to enable the management-vlan command. OSPF utilises addresses in vlan 1 for routing.

Re: DHCP Relay Bug?

Hiya,

I can do this on any of our edge switches as they all have 10.5.1.x addresses. They can ping 10.177.20.19 fine. Traceroute output is:

L5NR_2626PWR.1# trace 10.177.20.19
traceroute to 10.177.20.19 ,
1 hop min, 30 hops max, 5 sec. timeout, 3 probes
1 10.5.1.1 0 ms 0 ms 0 ms
2 10.177.20.19 0 ms 0 ms 0 ms

Re: DHCP Relay Bug?

Well that's the strange thing about this problem. Its random and sometimes clients are ok and sometimes not. Currently we've got issues with vlan 67 and 31.

Another development has been that some clients are having difficulty properly resolving DNS names, but testing on other clients in the same subnet works! Our of desperation I enabled ip directed broadcasts and those clients with problems immediately resolved the names. Based on what I know of this command however I'm not sure why it would fix it.

I don't think our issues our resolved with that one change. There's something else going on that we can't track down.
