25GbE SFP28 Port

Ports Te-1/1/25, Te-1/1/26, Te-1/1/27 and Te-1/1/28 are a group of ports, you should manually configure the port speed for these four ports by using the set interface gigabit-ethernet speed command before inserting an optical module. When configuring the rate, the supported port rates are 25 Gbit/s, 10 Gbit/s, and 1 Gbit/s. The four ports can be configured with the same port rate or different rate. When configured at different port rates, 10G and 1G can coexist, but 25G cannot coexist with other rates. The following table gives several cases of speed setting for this group of ports.

Note: If the port rate is set to 25 Gbit/s, but a 10 Gbit/s optical module is inserted, the port cannot go up.

 

HiGig2 stacking ports

N3224P-ON has one slot for QSFP module at the rear side which can be plugged in 2 x 100G QSFP modules. The port numbers of the QSFP module are x-1/1/1 and xe-1/1/2. They can be used as normal 100G QSFP28 ports.
