You can try to specifically block the ethertype 0x86DD in a mac access list and see if that stops the ipv6 traffic. Yes, 3550's will act the same way. Scott

Adding IP access-list to the Vlan Access-map allowed me to ping the hosts. Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 8/28/42 ms 3560#ping 192.168.1.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 9/21/42 ms Does this ASIC behaviour is similar to CAT 3550 as well? There is nothing mentioned in the DOC CD. The IPV6 traffic still goes through. The VLAN access map does not accept "match ipv6 address". I am just looking for other ways to block the IPV6 traffic :( Sharath
