Configuring MLS
We recommend that you keep the size of the MLS cache below 32,000 entries. If the number of MLS
Note
entries exceeds 32,000, some flows are sent to the MSFC. To keep the size of the MLS cache down, for
IP, enable IP MLS fast aging as described in the
Aging Time, and Packet Threshold Values" section on page
To specify the MLS aging time for both IP and IPX, perform this task in privileged mode:
Task
Specify the MLS aging time for MLS cache entries. set mls agingtime [agingtime]
This example shows how to specify the MLS aging time:
Console> (enable) set mls agingtime 512
Multilayer switching agingtime IP and IPX set to 512
Console> (enable)
To specify the IP MLS aging time, perform this task in privileged mode:
Task
Specify the IP MLS aging time for an MLS cache
entry.
This example shows how to specify the IP MLS aging time:
Console> (enable) set mls agingtime ip 512
Multilayer switching aging time IP set to 512
Console> (enable)
To specify the IPX MLS aging time, perform this task in privileged mode:
Task
Specify the IPX MLS aging time for an MLS
cache entry.
This example shows how to specify the IPX MLS aging time:
Console> (enable) set mls agingtime ipx 512
Multilayer switching aging time IPX set to 512
Console> (enable)
Specifying IP MLS Long-Duration Aging Time, Fast Aging Time, and Packet Threshold Values
Note IPX MLS does not use fast aging. IPX MLS only operates in destination-source and destination flow
modes; therefore, the number of IPX MLS entries in the MLS table is low relative to the number of IP
MLS entries in full-flow mode.
