We have a Brocade ICX7250 that will not stack. We atleast 40 sites with the same stack configuration. So this isn't a new setup for us.
When we do the 'stack enable' we receive the error: “stack port e 1/2/1 has 1g speed-duplex settings”. With stack cables you don't need the license for 10G for stacking. Stacking cables are connected via the standard, 1/2/1 to 1/2/3 to the second switch, and vice-versa for the return to complete the stack circle.
Is this a known issue with a fix for it?
Up to 12 ICX 7250-24, ICX 7250-24P, ICX 7250-48, or ICX 7250-48P units can be connected in a linear or ring topology. Any of these models can be mixed in the same stack. Stacking ports are located on the front panel as shown in the following figures. NOTE
From one to four 10-Gbps ports (from eight available 10-Gbps ports) can be used for stacking on the ICX 7250. All stacking ports must have an active license installed to be properly configured. Active stacking ports can be configured in one of two sets of ports on the front panel; however, stacking ports cannot be mixed between the two sets of ports because of operational constraints. Available ports are numbered 1/2/1 through 1/2/8 as shown in the following figure.
