Helo, everyone i have a problem with my Cat6500 sup2/msfc2/pfc2
The approximate topologi is such:
PC(ip=10.0.5.254)---dummy switch---Cat6500.
Initial Catalyst port(to which pc is connected) in set to L2 access vlan 700, vlan700 SVI have ip unnumbered configuration, getting its IP from loopback700. If for example i'll set ip directly to vlan700 SVI, it works, but this is not what i need to obtain. When i run debug ip packet with ip unnumbered applied i get:
IP: s=10.0.5.254 (Vlan700), d=10.0.5.50, len 60, rcvd 2
IP: tableid=0, s=10.0.5.50 (local), d=10.0.5.254 (Loopback700)
IP: s=10.0.5.50 (local), d=10.0.5.254 (Loopback700), len 60, sending
IP: s=10.0.5.50 (local), d=10.0.5.254 (Loopback700), len 60, sending full packet
IP: tableid=0, s=10.0.5.50 (Loopback700), d=10.0.5.254 (Loopback700), routed via
RIB

So, as i see Cat recieves and sends replies, but they never reach PC. Whith additional debug arp i got:
IP ARP req filtered src 10.0.5.254 00a1.b000.aab6, dst 10.0.5.50 0000.0000.0000
wrong cable, interface Vlan700
After google-search i found that "wrong cable, interface" indicates that incoming packet is from different subnet and device will simply assume that it cannot be such situation and drop the packet - but this is not situation of mine - cause i have same subnet.
Any ideas for this?
