Symptom

+ Need to mix 40G and 10G interfaces

Conditions

+ Using a BiDi 40G QSFP on Eth1/49 to illustrate: switch(config-if)# show int eth1/49 transceiver Ethernet1/49 transceiver is present type is QSFP-40G-SR-BD name is CISCO-AVAGO part number is AFBR-79EBPZ-CS2 revision is 01 + Here are the QSFPs (QSAs) on Eth1/52 and Eth1/53 to illustrate: Ethernet1/52 transceiver is present type is QSFP-Cazadero name is CISCO-DNI part number is CAZADERO-R revision is 03 nominal bitrate is 10000 MBit/sec per channel switch(config-if)# show int eth1/53 transceiver Ethernet1/53 transceiver is present type is QSFP-Cazadero name is CISCO-DNI part number is CAZADERO-R revision is 03 nominal bitrate is 10000 MBit/sec per channel + This is the configuration that needs to be added: switch(config)# interface breakout module 1 port 52-53 map 10g-4x switch(config-if)# show int br | i up mgmt0 -- up 10.122.160.192 100 1500 Eth1/49 -- eth routed up none 40G(D) — << Running 40G Eth1/50 -- eth routed up none 40G(D) -- Eth1/52/1 -- eth routed up none 10G(D) — << Broken out to 10G Eth1/53/1 -- eth routed up none 10G(D) -- << Broken out to 10G

Workaround

+ This is the configuration that needs to be added: switch(config)# interface breakout module 1 port 52-53 map 10g-4x
