What is the recommended maximum number of 3750s to place in a stack, and what performanc
e issues can I expect to see (CPU, memory, SNMP drops, etc.,) as that number is approached?
Up to nine separate switches can be joined together through their StackWise ports.
One of the switches controls the operation of the stack and is called the stack master. The stack master and the other switches in the stack are stack members. The stack members use the Cisco StackWise technology to behave and work together as a unified system. Layer 2 and Layer 3 protocols present the entire switch stack as a single entity to the network.
StackWise Plus technologies deliver advanced performance for voice, video, and Gigabit Ethernet applications.
Problem can be faced is a break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. Subsecond timing mechanisms detect traffic problems and immediately institute failover. This mechanism restores dual path flow when the timing mechanisms detect renewed activity on the cable.
I guess I wasn't clear enough. I want to add additional switches to my stack, but need to first confirm that the StackWise cabling is redundant, or else I run the risk of isolating part of the stack when I disconnect the StackWise cables to insert the new switch into the stack. How is this determined via CLI?
We are pleased to announce availability of Beta software for 16.6.3. 16.6.3 will be the second rebuild on the 16.6 release train targeted towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are looking for early feedback from custome...
