[c-nsp] 6500 not supporting md5 on HSRP?

[Rutger Bevaart]

Hello list,

On a sup32 running s3223-ipservicesk9_wan-mz.122-18.SXF9.bin I am unable
to configure md5 authentication HSRP for VLAN interfaces...

On a 3560 I am able to (under interface configuration) do:

"standby 1 authentication md5 key-string 7 <encrypted md5 string>"

I checked with sup32 and sup720's, and it does not support md5. Is this
available in other releases or just a missing feature on the MSFC's?

regards,
Rutger
