Hi James,

I would log a JTAC call for that bug and see if there is a PR for that.

Ta,

Hijack time

Has anyone seen an issue with a SRX110 where the ADSL will not negotiate unless you restart FPC 1 which has the ADSL module?  This happens on boot and if the DSL drops. When I say negotiate I mean the AT-1/0/0.1 interface is up but no PPP. Restart the FPC and it will start working.

I've seen this on 11.3r,11.4r2-4 and 12.1r1


/hijack over


Thanks

I have had a couple of issues with my SRX100 where it stops forwarding traffic. Nothing seems to bring it back except a reboot.

Would notice it when I get home and I have no Internet. Cant SSH in or ping through it to another subnet in a different VLAN, so I break out the USB-Serial adaptor. PPPoE has dropped and no amount of clearing PPPoE sessions would make it come back.

Seems to be running fine now that I have updated to 12.1R3.5, which also fixed a "bug" where SNMP would just stop returning current values. It would return the same values over and over, so SNMP itself hadnt broken, just not current ones.

Tom
