work on M-EOS or third party switches. Figure 47 shows a switch in AG mode without F_Port masterless
trunking. Figure 48 shows a switch in AG mode with F_Port masterless trunking.
Figure 47 Switch in Access Gateway mode without F_Port trunking
Figure 48 Switch in Access Gateway mode with F_Port masterless trunking
NOTE: You do not need to map the host to the master port manually because Access Gateway performs
a cold failover to the master port.
To implement F_Port masterless trunking, you must first configure an F_Port trunk group and statically assign
an Area_ID within the trunk group. Assigning a Trunk Area (TA) to a port or trunk group enables F_Port
masterless trunking on that port or trunk group. When a TA is assigned to a port or trunk group, the ports
immediately acquire the TA as the area of its PID. When a TA is removed from a port or trunk group, the
ports will revert to the default area as its PID.
