Information About Broadband IPv6 Counter Support at LNS

Broadband IPv6 Counter Support at LNS

This feature provides support for broadband PPP IPv6 sessions at the layer 2 tunneling protocol (L2TP) network server (LNS). The sessions are forwarded by L2TP access concentrator (LAC) using layer 2 tunneling protocol L2TP over IPv6.

This feature is enabled automatically when the user configures LNS and enables IPv6.

How to Verify Broadband IPv6 Counter Support at LNS

Verifying Broadband IPv6 Counter Support at the LNS

This feature is enabled automatically when the user configures LNS and enables IPv6. To verify information about this feature, you can use any or all of the following optional commands as needed.

SUMMARY STEPS

  1. enable
  2. show l2tp session [all | packets [ipv6 ] | sequence | state | [brief | circuit | interworking ] [hostname ]] [ip-addr ip-addr [vcid vcid ] | tunnel {id local-tunnel-id local-session-id | remote-name remote-tunnel-name local-tunnel-name } | username username | vcid vcid ]
  3. show l2tp tunnel [all | packets [ipv6 ] | state | summary | transport ] [id local-tunnel-id | local-name local-tunnel-name remote-tunnel-name | remote-name remote-tunnel-name local-tunnel-name ]
  4. show l2tun session [l2tp | pptp ] [all [filter ] | brief [filter ] [hostname ] | circuit [filter ] [hostname ] | interworking [filter ] [hostname ] | packets ipv6 ] [filter ] | sequence [filter ] | state [filter ]]
  5. show vpdn session [l2f | l2tp | pptp ] [all | packets [ipv6 ] | sequence | state [filter ]]
  6. show vpdn tunnel [l2f | l2tp | pptp ] [all [filter ] | packets ipv6 ] [filter ] | state [filter ] | summary [filter ] | transport [filter ]]

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Router> enable

Enables privileged EXEC mode.
