I have a 3750 switch configured with 2 L3 ports but I cannot ping from
one interface to the other. I normally just do IP addresses on VLAN and
perform intra-vlan routing but I would assume this would work the
same....any ideas..?
xxx-02#ping 10.63.7.6 source 10.63.7.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.63.7.6, timeout is 2 seconds:
Packet sent with a source address of 10.63.7.2
.....
Success rate is 0 percent (0/5)
xxx-02#ping 10.63.7.6 source 10.63.7.5
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.63.7.6, timeout is 2 seconds:
Packet sent with a source address of 10.63.7.5
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/8 ms
