Port Monitoring

The Aggregator supports multiple source-destination statements in a monitor session, but there may only

be one destination port in a monitoring session (Message 2).

The number of source ports supported in a port pipe is equal to the number of physical ports in the port

pipe. Multiple source ports may have up to four different destination ports (Message 3).

In Figure 15-1, ports 0/13, 0/14, 0/15, and 0/16 all belong to the same port-pipe. These ports mirror traffic

to four different destinations (0/33, 0/34 0/35, and 0/37). Another source port from the same port-pipe (for

example, 0/17) does not support a new destination (for example, 0/40). If you attempt to configure another

destination, an error message is displayed (Message 3). However, you can configure another monitoring

session that uses one of previously configured destination ports.
