WCCP Mask change in 4.2.3c

[dhanasekaran.r]

Hi All,

We upgraded the WAE from 4.1.5f to 4.2.3c. We did not disable WCCP in the IOS router before and after the upgarde so the Mask assignment remained the same ( 0x1741).

We have the situtaion where , we need to add a new WAE with code with code 4.2.3c to existing setup which has existing WAE.

How do we change the WCCP Mask assignment to 0xF00 in the IOS router so that we can make both WAE to work in load sharing basis.

Thanks,

Hi Dhana,

As long as your wae running 4.2.3 is configured for mask assignment the default value is 0XF00 and you do not need to make any changes on the IOS router for mask assignment.

When you enable wccp on wae running 4.2.3c code it will let the router know about the default mask.

Dhana,

Before adding the 4.2.3 WAE to this farm which should have the default mask of 0xF00 configured already, you will need to go to the CLI of the other two WAEs that were upgraded from 4.1.5 and execute the config command  "wccp mask is src-ip-mask 0xf00 dst-ip-mask 0x0"

Then all three WAEs will have the same mask value, and it will be safe to bring the 3rd WAE into this farm.

No configuration changes are required on the router.

Hi Mike,

Thanks, the WCCP command in the WAE helped to bring both WAE to the same farm.
