Trunk monitoring
To monitor E_Port (ISL) and F_Port trunks, you can set monitors only on the master port of the trunk. If
the master changes, the monitor automatically moves to the new master port.
If a monitor is installed on a port that later becomes a slave port when a trunk comes up, the monitor
automatically moves to the master port of the trunk.
Trunk monitoring considerations
• End-to-end (EE) monitors are supported for ISLs only on the Brocade 6505, 6510, 6520, M6505,
6547, and DCX 8510 family.
• If an EE monitor is installed on a trunk group and you disable the trunk, the EE monitor will be
installed only on the last master port of that trunk group, which may not be the actual port on which
the EE monitor was installed when the trunk was enabled.
• For F_Port trunks, end-to-end masks are allowed only on the F_Port trunk master. Unlike the
monitors, if the master changes, the mask does not automatically move to the new master port.
• All platforms support 12 frame monitors for trunks, except for the Brocade 300, which supports 8
frame monitors for trunks.
Saving and restoring monitor configurations
To prevent the switch configuration flash from running out of memory, the number of monitors saved to
flash memory is limited as follows:
• The total number of EE monitors per port is limited to 16.
• The total number of frame monitors per port is limited to 16.
• The total number of monitors per switch is limited to 512.
When there are more than 512 monitors in the system, monitors are saved to flash memory in the
following order:
