Switching

Hi.

I have a completly new ex3400 VC setup where I have issues to commit a configuration with rstp edge configuration set to a interface range.

The stack consists of 7 x ex3400-48T running JunOS 18.2R3-S4.1.

If I just take one random interface and issue the command set protocol rstp interface ge-6/0/1 edge and do a commit, the configuration is commited. But if instead do set protocol rstp interface AccessPort-BaseConfig edge and do a commit I get this error message:

error: Unique id allocation failed for '//var/etc/stp_port.id' - no more free ids
error: Failed to allocate unique port-id for xSTP - likely due to exceeding the number of user configurable STP ports which is 4095
error: foreign file propagation (ffp) failed

The interface range configuration looks like this:

interfaces {
    interface-range AccessPort-BaseConfig {
        member-range ge-0/0/0 to ge-6/0/47;
        unit 0 {
            family ethernet-switching {
                interface-mode access;
                storm-control default;
            }
        }
    }

This is working on at least two other setups running the smae JunOS version.I have tried to reboot the stack completly, with the same result.

Any ideas?

Best regards,
Johan Christensson

Hi Johan,

This seem to be a known issue, you can find it below,

https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR1366903

The best way to proceed will be changing the ranges to a minor range as the example provided on the PR,

set interfaces interface-range  jtac-test1 member-range ge-0/0/0 to ge-6/0/47
set interfaces interface-range jtac-test1 member-range ge-7/0/0 to ge-8/0/47
set interfaces interface-range jtac-test2 member-range ge-7/0/0 to ge-8/0/47
set interfaces interface-range jtac-test2 member-range ge-0/0/0 to ge-6/0/47

Pleas try the workaround to double check.

If this worked for you please mark as "Accepted Solution" so we can help others too 🙂

Hi Johan,

Can you please try setting the member range as:

set interfaces interface-range AccessPort-BaseConfig member-range ge-0/0/0 to ge-0/0/47

set interfaces interface-range AccessPort-BaseConfig member-range ge-1/0/0 to ge-1/0/47

set interfaces interface-range AccessPort-BaseConfig member-range ge-2/0/0 to ge-2/0/47

set interfaces interface-range AccessPort-BaseConfig member-range ge-3/0/0 to ge-3/0/47

set interfaces interface-range AccessPort-BaseConfig member-range ge-4/0/0 to ge-4/0/47

set interfaces interface-range AccessPort-BaseConfig member-range ge-5/0/0 to ge-5/0/47

set interfaces interface-range AccessPort-BaseConfig member-range ge-6/0/0 to ge-6/0/47

Also, just to double confirm on the PR mentioned, what is the output for:

show interfaces | display set | display inheritance | count

Hi all and thanks for the quick reply.

After that I changed the interface-range to look like the below, the configuration was commited.

interfaces {
    interface-range AccessPort-BaseConfig {
        member-range ge-0/0/0 to ge-0/0/47;
        member-range ge-1/0/0 to ge-1/0/47;
        member-range ge-2/0/0 to ge-2/0/47;
        member-range ge-3/0/0 to ge-3/0/47;
        member-range ge-4/0/0 to ge-4/0/47;
        member-range ge-5/0/0 to ge-5/0/47;
        member-range ge-6/0/0 to ge-6/0/47;
        unit 0 {
            family ethernet-switching {
                interface-mode access;
                storm-control default;
            }
        }
    }

Hi Johan,

I believe separating the member ranges to work. This will ensure that the pool size is reduced. You can try splitting up the ports in the below range,

 ge-0/0/0 to ge-6/0/47;

 you can split it up and check if that helps.
