Verification Example for the show ppp multilink Command
Example 22-13 shows sample output from the show ppp multilink command. In the example,
information about the MLP over ATM bundle (Multilink3) displays first. Information about the member
links then displays, including the number of active and inactive member links. Class fields are omitted
from the output; everything is implicitly in receive class 0 and transmit class 0.

The following list describes the bundle-level fields and lines in the show ppp multilink command
output:
• Bundle name is name—The bundle identifier for the bundle.
• Bundle up for time—The elapsed time since the bundle first came up.
• load n/255—The traffic load on the bundle as multilink computes loads for bandwidth-on-demand
purposes. This load might count all traffic, or just inbound or outbound traffic, depending on the
configuration.
• Receive buffer limit n bytes—The maximum amount of fragment data that multilink can buffer in
its fragment reassembly engine for each receive class. This amount is derived from the configured
slippage constraints.
