Usage

A VSX LAG across a VSX device can have at most a total of eight interfaces. A VSX LAG must be LACP-based. A non-LACP/static VSX LAG is not supported.
NOTE:

When creating a VSX LAG, select an equal number of member links in each segment for load balancing, such as four member links (one segment) and four member links (another segment). Do not create a VSX LAG with six member links in one switch and two member links on another segment.

Example

Configuring LAG 100 as a VSX LAG:

switch(config)# interface lag 100 multi-chassis

Removing LAG 100 as a VSX LAG:

switch(config)# no interface lag 100
