# Monitoring Multiclass MLPPP

#### Purpose

Display information about the status and configuration of multilink classes on an MLPPP Interface.

#### Action

To display configuration information about multiclass MLPPP member links configured in the specified MLPPP bundle:

    host1#show ppp interface mlppp bundle1 config
    PPP interface mlppp mlppp1 is up
    ...

    PPP multilink member-interface gigabitEthernet 3/0.1.1 is up
    Link interface administrative status is open
    PPP multilink multiclass is enabled
    PPP multilink multiclass classes 4
    PPP multilink multiclass fragmentation is enabled on “voice”, otherData”
    PPP multilink multiclass reassembly is enabled on “voice”, ”otherData”
    ...

    PPP multilink member-interface gigabitEthernet 3/0.1.2 is up
    Link interface administrative status is open
    PPP multilink multiclass is enabled
    PPP multilink multiclass classes 4
    PPP multilink multiclass fragmentation is enabled on “voice”,”otherData”
    PPP multilink multiclass reassembly is enabled on “voice”, ”otherData”
    ...
    1 mlppp interfaces found

To display the statistics of the multiclass MLPPP member links configured in the specified MLPPP bundle:

    host1#show ppp interface mlppp bundle1 statistics
    PPP interface mlppp bundle1 is up
    Time since last baseline 2 days, 18 hours
    2 receive classes, 2 transmit classes

    0x0 last received sequence number

    Transmit Class 0:
    0 fragments, 0x8 last sent sequence number

    Transmit Class 1:
