Re: telnet problem of 6500series switches

Hi,

Do u have connectivity to the management IP address. Can you ping to this IP from the desktop you are trying to telnet.

THe access layer switches require ip default-gateway configuration to access devices outside the network domain

configs would help

HTH, rate if it does

Re: telnet problem of 6500series switches

Hi

First verify which is u r management vlan.try to check weather this vlan is allowed on the trunk links connecting to u r dist.

u r default-gateway should be the SVI of the switch which is doing intervlan-routing.

Thanks

Re: telnet problem of 6500series switches

Check your vlans at layer 2 on both the dist and access switches . Do a show vlan and make sure they show active on both the dist and access switches . Also make sure the management vlan is allowed across the trunk on "both" the dist. and access switches . If these are trunked verify trunk is working correctly and the allowed vlans look correct "show int trunk" on both dist and access .Obviously if you cant telnet to the access switches you will have to verify the configs by plugging into the console ports on the access switches. Verify the layer3 SVI for your mgt. vlan shows up/up .

Re: telnet problem of 6500series switches

does anybody has the solution to my problem?....its really very critical

Re: telnet problem of 6500series switches

as already stated, do you have connectivity between the PC initiating the telnet and the switch.

Are they on the same subnet or different.

Also let me know whether you are able to reach the default-gateway IP mentioned in the switch configuration from the telnetting machine
