View TCP and UDP Information

Perform this procedure to view the TCP and UDP configuration information for IPv6.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display IPv6 TCP connection information:

    show ipv6 tcp connections [vrf WORD<1–16> | vrfids WORD<0–512>]

  3. Display IPv6 TCP listener information for the specified IPv6 address:

    show ipv6 tcp listener [vrf WORD<1–16> | vrfids WORD<0–512>]

  4. Display IPv6 TCP properties

    show ipv6 tcp properties [vrf WORD<1–16> | vrfids WORD<0–512>]

  5. Display IPv6 TCP statistics

    show ipv6 tcp statistics [vrf WORD<1–16> | vrfids WORD<0–512>]

  6. Display IPv6 UDP information:

    show ipv6 udp endpoints [vrf WORD<1–16> | vrfids WORD<0–512>]

Example

Switch:1>show ipv6 tcp connections
