NOTE: There is no limit to the number of monitoring sessions per system, provided that there are only four destination ports per
port-pipe. If each monitoring session has a unique destination port, the maximum number of session is four per port-pipe.
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.
There may only be one destination port in a monitoring session (% Error: Only one MG port is allowed in a session.).
The number of source ports the Dell Networking OS allows within a port-pipe is equal to the number of physical ports in the port-pipe (n).
Multiple source ports may have up to four dierent destination ports (Exceeding max MG ports for this MD port pipe.).
In the following examples, ports 0/13, 0/14, 0/15, and 0/16 all belong to the same port-pipe. These ports mirror trac to four dierent
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, 0/4). If you attempt to congure another destination, an error message is displayed: % Error: Exceeding
max MG ports for this MD port pipe. However, you can congure another monitoring session that uses one of previously
congured destination ports.
