DSCP rewrite on EX-2200

Hi

 

I have problem. In documentation I found:

 

http://www.juniper.net/techpubs/en_US/junos10.4/topics/concept/ex-series-software-features-overview....

Table 4: Class-of-Service (CoS) Features by Junos OS Release

 

Class of service (CoS)—Class-based queuing with prioritization; Layer 2 and Layer 3 classification, rewrite and queuing; strict priority queuing on egress

*10.1R1*

 

but some lines under this is:

 

Remarking of bridged packets:

*Not supported*

 

Is remarking something other than rewriting?

 

We want to rewrite packets on ex2200 dscp, but it is not supported as it is mentioned in the document.... "warning configuration block ignored: non supported platform (ex2200.....)"

 

Is this a typo? Shoud I open JTAC ticket? :smileyhappy:

 

Thanks

Re: DSCP rewrite on EX-2200

I agree the wording is quite confusing - I think what it's trying to say though is that the EX2200 supports rewriting of Layer 2 ToS bits (802.1P), but by the looks of it, it only supports this on routed (not RVI or ethernet-switching) interfaces.
