BigIron RX Series Configuration Guide 109353-1001986-01Displaying global IPv6 information 43Displaying IPv6 TCP informationYou can display the following IPv6 TCP information:• General information about each TCP connection on the router, including the percentage of freememory for each of the internal TCP buffers.• Detailed information about a specified TCP connection.To display general information about each TCP connection on the router, enter the followingcommand at any CLI level.Syntax: show ipv6 tcp connectionsThis display shows the following information.TABLE 176 IPv6 local router information fieldsThis field... Displays...Router <ipv6 address> on <interface><port>The IPv6 address for a particular router interface.Last update The amount of elapsed time (in minutes) between the current andprevious updates received from a router.Hops The default value that should be included in the Hop Count field of theIPv6 header for outgoing IPv6 packets. The hops value applies to therouter for which you are displaying information and should be followedby IPv6 hosts attached to the router. A value of 0 indicates that therouter leaves this field unspecified.Lifetime The amount of time (in seconds) that the router is useful as the defaultrouter.Reachable time The amount of time (in milliseconds) that a router assumes a neighbor isreachable after receiving a reachability confirmation. The reachabletime value applies to the router for which you are displaying informationand should be followed by IPv6 hosts attached to the router. A value of 0indicates that the router leaves this field unspecified.Retransmit time The amount of time (in milliseconds) between retransmissions ofneighbor solicitation messages. The retransmit time value applies to therouter for which you are displaying information and should be followedby IPv6 hosts attached to the router. A value of 0 indicates that therouter leaves this field unspecified.BigIron RX# show ipv6 tcp connectionsLocal IP address:port <-> Remote IP address:port TCP state192.168.182.110:23 <-> 192.168.8.186:4933 ESTABLISHED192.168.182.110:8218 <-> 192.168.182.106:179 ESTABLISHED192.168.182.110:8039 <-> 192.168.2.119:179 SYN-SENT192.168.182.110:8159 <-> 192.168.2.102:179 SYN-SENT2000:4::110:179 <-> 2000:4::106:8222 ESTABLISHED (1440)Total 5 TCP connectionsTCP MEMORY USAGE PERCENTAGEFREE TCB = 98 percentFREE TCP QUEUE BUFFER = 99 percentFREE TCP SEND BUFFER = 97 percentFREE TCP RECEIVE BUFFER = 100 percentFREE TCP OUT OF SEQUENCE BUFFER = 100 percent
