Extreme Networks inter-switch link trunks
In VCS mode, unless specifically disabled, inter-switch link (ISL) Extreme Networks trunking between adjacent devices is automatic. All
ports must be in the same port group and must be configured at the same speed. There is a limit of sixteen ports per trunk group. No
separate licensing is required. Refer to the illustrations below for the exact port groups. On the VDX 6740T, ports in groups 3 and 3A, as
well as port groups 4 and 4A, cannot be trunked together. However, these ports can be trunked on the VDX 6740 when the 40 GbE
QSFP ports are configured in breakout mode. VDX 6740T 1GbE ports cannot be trunked.
NOTE
If connections are made to 16 different switches, only eight ports will be trunk ports while the other eight ports will be normal
ISL ports.
For instructions on configuring breakout mode and Extreme Networks trunking, refer to the Extreme Network OS Management
Configuration Guide.
