What does the engineer need to configure to open the IPV6CP NCP on the link? The configuration on both ends need to be match for both Phase 1 and Phase 2 to be successful. there are 2 ways of doing this, For this you need to enable http server on your ASA and you need to know the credentials used to access asa via asdm (default is no username no password), asa(config)# crypto key generate rsa modulus 1024, Note: This is for creating keys because we communicate with asa via https, if you have ssh access you probably have these keys, Once you have enabled http server on asa go to your browser and give the following in the url field, https:///capture//pcap, if it is in multiple context mode you have to specify the context, https:///capture///pcap, After you enter this you will be prompted for username password and once you enter that the captures are stored on your PC and you can open them in a packet anaylser tool, As metioned before in some cases you might need to capture packets on devices directly connected to asa and in most cases it is a switch connected to ASA and in such cases you can also span the switchport to collect captures, Here is a link which will help you setup a span on your catalyst switch, http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml#config, Once done always make sure that you remove the captures using the command, To verify if ASA is dropping any packet - simple connectivity issues, access-list capi extended permit ip host 192.168.1.2 host 4.2.2.2, access-list capi extended permit ip host 4.2.2.2 host 192.168.1.2, capture capin interface inside access-list capi, capture capin interface inside match ip host 192.168.1.2 host 4.2.2.2, [this is possible in asa 8.0 and above and we do not need to be in config mode to put apply an capture], access-list capo extended permit ip host a.b.c.d host 4.2.2.2, access-list capo extended permit ip host 4.2.2.2 host a.b.c.d, capture capout interface outside access-list capo, capture capout interface outside match ip host a.b.c.d host 4.2.2.2, [Note that we are using the natted ip - so for capture use the ip addresses that you expect to see on the wire after all processing is done for egress interface and before any processing is done for ingress interface], We can also apply capture using ASDM and the below screen shots show the steps for that, 192.168.1.2 > 4.2.2.2: icmp: echo request, So you can see we have captured bidirectional traffic, If you want to see more details you can use the detailed keyword at the end, 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52241), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 16992), 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52242), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 16993), 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52243), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 17008), 000c.29d6.7dca 0026.0b09.420c 0x0800 74: 192.168.1.2 > 4.2.2.2: icmp: echo request (ttl 128, id 52244), 0026.0b09.420c 000c.29d6.7dca 0x0800 74: 4.2.2.2 > 192.168.1.2: icmp: echo reply (ttl 127, id 17251), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52241), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 16992), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52242), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 16993), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52243), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 17008), 0026.0b09.420d 0022.556d.f140 0x0800 74: a.b.c.d > 4.2.2.2: icmp: echo request (ttl 128, id 52244), 0022.556d.f140 0026.0b09.420d 0x0800 74: 4.2.2.2 > a.b.c.d: icmp: echo reply (ttl 127, id 17251).
