9600 Supervisor 1 vs 2

[Chris McCann]

Hi all,

We are looking at replacing our 6509E.

Currently the 9606 looks like the job, however we use a lot of 1GB SFP ports on the current 6509E.

With this in mind should we be using the Supervisor 1 cards, I am getting the impression that the Supervisor 2 doesnt support 1GB SFP?

I am looking at this document 

Migrating from Cisco Catalyst 6500/6800 to 9600 Series Switches

Under port density it doesnt have a reference for 1GB using the Supervisor 2.

I am assuming that the supervisor 2 supercedes supervisor 1, but looking at the above it seems may have to go with the older supervisor.

any advice welcome,

Chris.

Stacking with classic IOS is stable.  Very stable. 

Stacking and VSS with IOS-XE is highly unstable compared to standalone IOS-XE.  

A good example is FN74222 - Full or Partial Cisco 9800 Series Wireless Controller Configuration Loss after High-Availability Stateful Switchover Failover.  The 9800 may lose it's configuration during a failover because the "repm" process (only found in VSS) would lock up.  But this would not happen if the platform is in N+1 -- This will only happen if the platform are running the affected firmware version are in a VSS.

Another example is below: 

3850 stack, 16.12.6

The spike was when the stacking cable (Catalyst 3850) because un-secure.  Notice how fast the memory utilization ramped up before the switch crashed?

Hi Joseph,

The switch is handling our core, L3 SVI so all the VLANs. The 1GB ports are running the fibre to various switches distributed throughout the infrastructure. We are also using the supervisor 10GB ports for further distrubition whereby higher bandwidth is required.

Chris .

On that case, another chassis L3 switch would likely be a better choice.  The 9600 with sup1 should be fine, also, again, the 9400 series too.  Another series that might be considered is the Nexus series for an Enterprise core.

Talk to some 3rd party optics.  They can reflash a GLC-SX-MMD to be SFP-10G.
