Resolving Module 2 Mismatches in an ICX 7650 Stack
Follow these steps to correct a module configuration mismatch in an ICX 7650 stack.
- Enter the
show stackcommand to confirm that a unit has become non-operational due to a configuration mismatch.ICX7650-48P Router# show stack T=1d4h22m36.1: alone: standalone, D: dynamic cfg, S: static ID Type Role Mac Address Pri State Comment 1 S ICX7650-48P active 609c.9f52.6353 128 local Ready 2 S ICX7650-48P standby 609c.9f52.5a9b 0 remote Ready 3 S ICX7650-48ZP member 609c.9f52.32e3 0 remote NON-OP: config mismatch <-- Unit 3 non-operational 4 S ICX7650-48ZP member 609c.9f52.2743 0 remote Ready due to mismatch active standby +---+ +---+ +---+ +---+ -3/1| 1 |3/2--3/2| 4 |3/1--3/1| 3 |3/2--3/2| 2 |3/1- | +---+ +---+ +---+ +---+ | | | |--------------------------------------------------| Standby u2 - protocols ready, can failover Current stack management MAC is 609c.9f52.6353 Rear-module: config = oper = default: stack-100g Stack ports are operating at 100G.
The example shows a configuration mismatch on stack unit 3. - Use one of the following options to resolve an identified configuration mismatch:
- Option 1: In global configuration mode, enter
the
no stack unitcommand followed by the stack number of the offending device to remove the unit from the stack and allow it to rejoin.ICX7650-48P Router# configure terminal ICX7650-48P Router(config)# no stack unit 3
The example removes stack unit 3 from the stack and shows the unit rejoining the stack with the correct configuration.
- Option 2: In stack unit configuration mode for the non-operational unit, enter the
no module 2command to remove the incorrect module configuration, which allows the correct module information to be learned.ICX7650-48P Router# configure terminal ICX7650-48P Router(config)# stack unit 3 ICX7650-48P Router(config-unit-3)# no module 2
- Option 1: In global configuration mode, enter
the
- (Optional) Enter the
show modulecommand to verify that the new configuration for Module 2 has been learned.ICX7650-48P Router(config-unit-3)# show module Module Status Ports Starting MAC U1:M1 ICX7650-48P POE 48-port Management Module OK 48 609c.9f52.6353 U1:M2 ICX7600-2X40GQ 2-port 80G Module OK 2 609c.9f52.6384 U1:M3 ICX7650-2X100G 2-port 200G Module OK 2 609c.9f52.6388 U2:M1 ICX7650-48P POE 48-port Management Module OK 48 609c.9f52.5a9b U2:M2 ICX7600-2X40GQ 2-port 80G Module OK 2 609c.9f52.5acc U2:M3 ICX7650-2X100G 2-port 200G Module OK 2 609c.9f52.5ad0 U3:M1 ICX7650-48ZP POE 48-port Management Module OK 48 609c.9f52.32e3 U3:M2 ICX7600-2X40GQ 2-port 80G Module OK 2 609c.9f52.3314 U3:M3 ICX7650-2X100G 2-port 200G Module OK 2 609c.9f52.3318 U4:M1 ICX7650-48ZP POE 48-port Management Module OK 48 609c.9f52.2743 U4:M2 ICX7600-2X40GQ 2-port 80G Module OK 2 609c.9f52.2774 U4:M3 ICX7650-2X100G 2-port 200G Module OK 2 609c.9f52.2778The example displays the updated configuration of Module 2 in stack unit 3 as a 2-port 80-Gbps module. - (Optional) Enter the
