    Monitoring MLPPP Information Configured on PPP Interfaces

    Purpose

    Display statistics for MLPPP information configured on PPP interfaces.

    Action

    To display information about the MLPPP member links configured in bundle group1;

    host1#show ppp interface mlppp group1 members 
    PPP interface mlppp group1 is up 
     PPP multilink member-interface serial 2/0:1/1 is up 
     PPP multilink member-interface serial 2/0:2/1 is up 
     PPP multilink member-interface serial 2/0:3/1 is up 

    To display information about all MLPPP member links configured for all bundles:

    host1#show ppp interface mlppp members 
    PPP interface mlppp group1 is up 
     PPP multilink member-interface serial 2/0:1/1 is up 
     PPP multilink member-interface serial 2/0:2/1 is up 
     PPP multilink member-interface serial 2/0:3/1 is up 
    PPP interface mlppp group2 is up 
     PPP multilink member-interface serial 2/1:1/1 is up 
     PPP multilink member-interface serial 2/1:2/1 is up 
     PPP multilink member-interface serial 2/1:3/1 is up 
    PPP interface mlppp group3 
     No member-interfaces found

    To display information about all MLPPP encapsulated links, regardless of whether the links are members of an MLPPP bundle:

    host1#show ppp interface mlppp links
    PPP multilink interface serial 2/0:1/1 is up 
    PPP multilink interface serial 2/0:2/1 is up 
    PPP multilink interface serial 2/0:3/1 is up 
    PPP multilink interface serial 2/1:1/1 is up 
    PPP multilink interface serial 2/1:2/1 is up 
    PPP multilink interface serial 2/1:3/1 is up 

    To display configuration information about MLPPP member links configured in bundle group1:

    host1#show ppp interface mlppp group1 config
    PPP interface mlppp group1 is up
    Network interface administrative status is open
    Configured network protocol is IPCP
    PPP multilink member-interface ATM 10/0.10 is up
    Link interface administrative status is open
    Link interface fragmentation is enabled
    Link interface fragment size is 128
    Link interface reassembly is enabled
    Link interface administrative MRRU is 2000
    PPP multilink member-interface ATM 10/0.11 is down (lower layer down)
    Link interface administrative status is closed
    Link interface fragmentation is enabled
    Link interface fragment size is 128
    Link interface reassembly is enabled
    Link interface administrative MRRU is 2000
    PPP multilink member-interface ATM 10/0.12 is down (lower layer down)
    Link interface administrative status is closed
    Link interface fragmentation is enabled
    Link interface fragment size is 128
    Link interface reassembly is enabled
    Link interface administrative MRRU is 2000
    PPP multilink member-interface ATM 10/0.13 is down (lower layer down)
    Link interface administrative status is closed
    Link interface fragmentation is enabled
    Link interface fragment size is 128
    Link interface reassembly is enabled
    Link interface administrative MRRU is 2000
    1 mlppp interfaces found

    To display statistics about all configured MLPPP member links configured in bundle group1:
