Basic CMC Network Connection
CAUTION: Connecting the STK port to the management network can have unpredictable results. Cabling GB and STK to
the same network (broadcast domain) can cause a broadcast storm.
For the highest degree of redundancy, connect each available CMC to your management network.
Each CMC has two RJ-45 Ethernet ports, labeled GB (the uplink port) and STK (the stacking or cable consolidation port). With
basic cabling, you connect the GB port to the management network and leave the STK port unused.
Daisy chain CMC Network Connection
If you have multiple chassis in a rack, you can reduce the number of connections to the management network by daisy-chaining up
to four chassis together. If each of the four chassis contains a redundant CMC, by daisy-chaining you can reduce the number of
management network connections required from eight to two. If each chassis has only one CMC, you can reduce the connections
required from four to one.
When daisy-chaining chassis together, GB is the uplink port and STK is the stacking (cable consolidation) port. Connect the GB
ports to the management network or to the STK port of CMC in a chassis that is closer to the network. You must connect the STK
port only to a GB port further from the chain or network.
Create separate chains for CMCs in the active CMC slot and the second CMC slot.
The following figure illustrates the arrangement of cables for four daisy-chained chassis, each with active and standby CMCs.
