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.

the access switch does not have a default ip route enabled. its connected to the main switch via trunk port.

For start:

Check are downstream switches connected to correct interfaces (if cdp is enabled):
sh cdp neigh

Check do trunk allow VLANs and are all VLANs present on all switches
sh int trunk
sh vlan brief

If everything looks OK, please sent topology drawing and configurations (remove sensitive parts).

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

Dear,

If you don't have interface  vlan configured in the switch you will not be able to ping the gateway, also you need the default gateway to be configured in order to ping other vlans.
