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:

Meaning

Table 31 lists the show ppp interface mlppp command output fields.

Table 31: show ppp interface mlppp Output Fields

Field Name

Field Description

PPP interface mlppp bundleName

Name and state (up or down) of the MLPPP interface

PPP multilink member-interface interfaceName

Name and state (up or down) of the MLPPP member link interface
