asked on

unable to reach any vlan gateways from access switch, ip phones connected are working but.

Two cisco switches connected via trunk port. can ping all vlan gateways from the core switch which has got route defined.on the second switch cannot ping any of the vlan ip addresses.  happend after cable rearrangement. on the second switch have clients connnected via ip phones and they are working ok however.

any advice.

vlan 10 - 192.168.10.x
vlan 30 - 192.168.30.x
vlan 20 -192.168.20.x
vlan 80 -19.168.80.x

gateway of last resort setup on the mains witch to 0.0.0.0 192.168.80.1. can see all VLAN allowed via trunk port. cant see any problem with cabling either.

both are cisco switches.

can ping all the vlan ip addresses and individual hosts from the core switch.
the access switch does not have a default ip route enabled. its connected to the main switch via trunk port.

It detects the core switch and vice versa for cdp.

Same with allowed vlans. It's set to all
Without more information it is just guessing game.
Please provide if possible:
- topology with marked interfaces
- output from all involved switches - commands (remove sensitive parts and replace ip addresses in output):
   show run
   show cdp
   show int status
   show vlan brief
