CAT 6506

we are planning to put redundant SUP 2 for our CAT 6506

Currently the CAT 6506 is booting from boot system flash disk0:s222-advipservicesk9_wan-mz.122-18.SXF10a.bin so the secondary SUP 2 which I am inserting whether it should also be boot from disk 0

Can I know what is difference between Slot0 and Disk 0

Is it depence on the compact flash ?

Re: CAT 6506

It depends on the hardware.

Some hardwares call their flash card compartiment: slots and other hardware call them disk.

So depending on what platform you are on it will use either:

slot0, slot1 OR disk0, disk1.

you can not use disk0 on a platform that uses slot0.

In your case on sup2 it's disk0:, disk1:

Re: CAT 6506

Thanks for your reply

so it depends on the PCMCIA Flash card

Currently we using the SUP 2 in SLOT 1 of the 6506 chassis

now we are going to put the same IOS and same model SUP2 on the SLOT 2 of the 6506 chassis

In live can we put the secondary SUP ?

i am configured SLOT 1 SUP redunanacy mode as SSO

what is difference between RPR+ and SSO ?

in this condition SLOT 1 will be master and synch all config to SLOT 2

Am i right


Re: CAT 6506

For the older ATA flash cards, I believe 20MB and below, the file system name was Slot0:, now with the higher capacity compact flash cards the switch calls the file system disk0: or disk1: depending which slot you use in the sup.
