Here is my case: ******************************** 2 Catalyst 2924XL : ******************************** CAT_1 configuration (simplified) ! interface FastEthernet 0/22 ! interface FastEthernet 0/23 port group 1 ! interface FastEthernet 0/24 port group 1 ! interface VLAN1 ip address 10.5.30.253 255.255.255.0 ip default-gateway 10.5.30.254 ! ******************************** CAT_2 Configuration (simplified) ! interface FastEthernet 0/22 ! interface FastEthernet 0/23 port group 1 ! interface FastEthernet 0/24 port group 1 ! interface VLAN1 ip address 10.5.30.252 255.255.255.0 ip default-gateway 10.5.30.254 ! ******************************** Hope the above info is enough. Problem: I am able to telnet both Catalysts from a PC from a 10.5.31.0/24 network, but I can't telnet/ping from CAT_1 command line interface to CAT_2 VLAN1 ip or e versa. Is the problem caused by FEC between them? Any suggestion.
