SCCP precedence

Whats the purpose of this command ?

sccp ip precedence <precedence>.

According to this link

http://www.cisco.com/univercd/cc/td/doc/product/software/ios123/123tcr/123tvr/vrht_s01.htm#wp1245396

highest value is 1 and lowest value is 7. Doesnt make sense. And default is 5.

Re: SCCP precedence

The command sets the IP Precenence/TOS value for SCCP packets. The highest/lowest labels don't really make sense. The only thing I can figure is that they meant highest/lowest probability of being dropped/delayed.

Re: SCCP precedence

Brandon,

So shouldnt these packets be marked with precedence 3 and not precedence 5 ?

Re: SCCP precedence

Sankar,

That's what I thought as well. The default precedence for phone SCCP traffic is 3, but can be configured per cluster. Evidently the default for gateway SCCP traffic is 5. If you do a "show sccp" on a gateway with no "sccp ip precedence" configured, you will see that it shows IP Precedence of 5. You learn something new every day.

Thanks for confirming that.

Cheers!
