ERS8800 bandwidth reduced after upgrade
« on: May 28, 2014, 03:23:08 PM »

I would really appreciate if someone could help me with an issue i recently found in my network (see attachment) after upgrading ERS8800s from version 7.1.0 to 7.2.10.

- I have two layer 2 ERS5698 connected to two ERS8800s via dual SMLT links.
- Theres an IST between the two ERS8800s
- Each 8800 connects individually to a L3 ERS5698 via LACP ( 4 links of 1 Gig each)

Before the upgrade, I used to be able to successfully send two streams of approx 900MB across the LAG ..from ERS5698 "E"and "F"  to ERS5698 "B" ( See diagram - Stream1 - from K to M; and Stream2 - from L to N). After the upgrade, only one stream is fully sent. The other stream starts dropping any traffic beyond 570MB.

The same behavior is observed when traffic is sent between the 2 L2 ERS5698s "E" and "F" though the ERS8800: only 570MB of the test 900MB is sent... the rest gets dropped.

Has anyone faced this type of situation before? Any suggestions?

Any port level errors?  What version are the 5698's running?
