Have been experiencing a lot of issues with OIR with SFPs in the new ASR920 Platform (ASR-920-24SZ-M)
eg.
%TRANSCEIVER-3-CHECKSUM_ERROR: F0: iomd: Detected in the transceiver module in TenGigabitEthernet0/0/27, module disabled
also
%TRANSCEIVER-3-INIT_FAILURE
or
just a no show, no log errors but ...
sw1#show hw-module all entity
…
transceiver 24
container index: 695
module entity index: 0
port index: 0
chassis index: 0
operational status: (0) error
non-zero xcvr sensors:
========================
.
After trying multiple IOS versions and trains, this issue appears to have all been fixed in
asr920-universalk9_npe.03.16.03a.S.155-3.S3a-ext.bin
All SFPs work reliably now including BXU/D, 10G-LR, 10G-ER etc
Cisco yet to post release notes for this IOS but I can't fault it in our network.
Notes:
1) Still obey the recommendation of waiting 30sec between removal and insertion of an SFP
2) Additionally upgraded to latest rom-mon too but was the IOS version above where all magically came good
upgrade rom-monitor filename bootflash:asr920-rommon.155-3r.S1.pkg r0
