VCSP ??

Hi just seen virtual chassis split-protection in version 734, anyone got any docs to explain this, I am familiar with RCD protocol.

Thanks

Hi,
in my knowledge VCSP (virtual chassis split protection) in 7.3.4 and 8.1.1 uses the same protocoll/function like SSP (Stack split protection). For this you will find infos at docu for 6850E and 6450/6250. You need a helper-switch (AOS 6.4.6, 6.6.4 or 8.1.1) with a linkagg to all chassis in VC (or stack). In my case I have a VC or Stack with 4 chassis. So I need a LAG with 4 ports to the helper.

command at VC/Stack
in R8 / R7.3.4

Code: Select all

-> virtual-chassis split-protection linkagg 4
-> virtual-chassis split-protection admin-state enable

in R6

Code: Select all

-> stack split-protection linkaggid 4
-> stack split-protection enable

command at helper
in R8

Code: Select all

-> virtual-chassis split-protection helper linkagg 4
-> virtual-chassis split-protection helper admin-state enable

or in R6

Code: Select all

-> stack split-protection helper linkagg 4
-> stack split-protection helper enable

RCD needs the EMP and often this link uses the same way like the VFL. So in error case it's possible that both (RCD and VFL) are broken. Than there is no protection.
