2960 switch no Management Access.

[RAMEEZ RAHIM]

We  have a 2960 switch (switch2), whose Management IP cannot be reached/Ping'd.

Could not Ping

We have checked the following, but still no clue on the root cause. Haven't tried a reboot yet.

Topology.

All swithces are cascaded through trunk and allows all vlan's.

L3switch1 <-> switch1 <-> switch2 <-> switch3 <-> L3switch2

• Switch 2 has correct ARP entries for the other switches that we try to ping.
• Mac addres table is fine.
• Switches other than Switch 2 has proper ARP and Mac entries.
• This Mgmt vlan is not pruned across any trunks. (we are able to ping switch3 crossing switch2 when tried from switch1)
• Switches are running PVST and convergence is fine.
• No access list to deny the traffic.
• Tried sut/no shut on the Vlan interface.

But still switch 2 could not be reached.

I think you might have missed to configure L3 virtual interface to access the L2switch.

Have you assigned an IP for SVI created on the switch. i.e Management Vlan?

If yes

were you able to access the switch 2 being on the same rather than from other switches?

[RAMEEZ RAHIM]

Yes, a SVI exist - i see it up/up.

[srikanth ath]

can you try to access switch2 from being on the same by connecting to one of the  access port of it which belongs to  Management vlan. ]

and please provide the folowein o/p.

sh cdp neighbors from switch1  or switch3
