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 different 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 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, 0/4). If you attempt to configure another destination, an error message is displayed: %
Error: Exceeding max MG ports for this MD port pipe. However, you can configure another monitoring session
that uses one of previously configured destination ports.

In the example below, 0/25 and 0/26 belong to Port-pipe 1. This port-pipe has the same restriction of only four destination
ports, new or used.
