# Monitoring the Number of MLD Groups on a Port

#### Purpose

Display the number of MLD groups that ports have accepted and, if configured, the maximum number of groups that ports can accept. A value of –1 indicates that no port group limit is configured. Only ports that have accepted MLD groups and ports for which you have configured a limit for the number of MLD groups appear in this display.

#### Action

To display the number of MLD groups that ports have accepted and the maximum number of groups that ports can accept:

    host1:boston#show multicast group limit
    Port      limit count
    --------- ----- -----
    2/0           5     0
    2/1          -1     1
