Dears,
Please check below configuration for my catalyst switch 3560. The hosts in VLAN 30 (10.0.30.5) can't ping hosts in VLAN 50 (10.0.50.5), however the hosts in VLAN 30 can ping interface VLAN 50 (10.0.50.1) and vice verse. please check configuration of the switch and let me know if you have any suggestions for such a problem.
