Wired Intelligent Edge

I am experiencing rx-discard between my HP 5406 zl2 core switch and 2530 48G edge switch.
There is a 700 MB/s data flow from the core switch to the edge switch. Tx discard is too high at 5406. I'm experiencing freezing in camera images.  There is fiber optic between the core switch and the edge switch. I am using 1 GB sfp. Is there a solution?

Thanks!

We cannot say that the port efficiency is 70%. When I increase the traffic, it can reach 1000 Mbit.

Hi @parnassus, Hi @dolanbay,

i cannot iagine that one of the two transceivers is original HPE.

1. Transceiver (B1) has a generic serial and reports no DOM (starting with C-Revision there was DOM on Board)
2. Transceiver (49) shows the wrong allowed distance (20km instead of 10km - see attached screenshot)

We cannot say that the port efficiency is 70%. When I increase the traffic, it can reach 1000 Mbit.

We use Longline J4859C 1000Base LX 1310nm 10km SFP Module HP compatible. 

i tired

int 49 rate-limit mcast in percent 100

b1 rate-limit mcast in percent 100

but it didn't work

If I were you (clearly if budget permits) I would use a pair of the original OEM supported (by an updated Aruba 5400R zl2 and and updated Aruba 2530) LX SFP Transceiver by HPE Aruba Networking, that is a pair among those:

• HPE X121 1G SFP LC LX Transceiver (J4859C) <--------------------------------- preferred
• Aruba 1G SFP LC LX 10km SMF Transceiver (J4859D) <---------------------- alternative to J4859C
• Aruba 1G SFP LC LX 10km SMF TAA Transceiver (JL746A) <----------------- Updated AOS-Switch software needed
• Aruba 1G I-Tmp SFP LC LX 10km SMF Transceiver (JL781A) <-------------- Updated AOS-Switch software needed

and - in any case - will try without the "rate-limit multi-cast" interface option (at least initially) to see how the connectivity over your Single Mode 9/125 um optic link (=<10 km) behaves.

For sure original OEM Transceivers support DOM, with non original part there is nothing granted (neither pure performances).
