Hi all,

Does anyone have any in depth information or official document about how ISSU works with VSS in conjunction ?

Thanks in advance.

Cheers.

ISSU that allows you to upgrade the full image in a dual Sup system (chassis or VSS). The caveat here is that a SW upgrade needs to happen on linecard as well. With VSS (and dual homed access devices) you have the advantage of linecard ports in different chassis . hence, un-interrupted connectivity.

Currently a full software upgrade isn't supported in a VSS setup. That functionality will come when SXI is released. Details should be included in the config guide for SXI when available. :)

If you are attending Networkers in Orlando, we will cover the ISSU upgrade in DETAIL :)
