M4300-28G ip management port fails after restart in a stacked configuration.
Hello, we have a stacked configuration from 6 times a M4300-28G switch (firmware version 12.0.2.9), the stack up and running. The ip management port (IP4) is set to vlan 1 and via the web inter...
Hi Jos,
We have received the TechSupport file just you sent to us.
This error may cause by serviceport enhancement in 12.0.2.x which add a new default IP address 192.168.0.239/24.
We also find a similar issue just like yours which will only appear on slave stack unit.
Maybe this issue have same root cause with yours.(default serviceport IP address)
So We will share the new firmware to you when the similar issue fix.
Please use a workaround method to avoid the error for now if possible:
Set the an another IP address on management VLAN.
Such as:
192.168.1.x/24
192.168.10.x/24
Thanks for your understanding and patience.
Hi Jos,
We have reproduced a similar issue just like yours.
I want to confirm that which unit connected with management port when you faced this issue?
in other words, Did you see this issue when the management port connected to master unit?
You can use following commands to check which unit is master.
1. Login switch and input username&password
2. Enable.
3. Show switch
Hello Daniel,
in our situation it makes no sense of the managemement port is connected with the master unit or another unit in the stack, in both cases ip management fails after restart.
When I change the ip-address (see below) to another address and back again to the original value then the Web Interface will working again.
(M4300-28G) (Config)#ip management vlan 1 192.168.4.2 255.255.0.0
(M4300-28G) (Config)#ip management vlan 1 192.168.4.1 255.255.0.0
Or disconnecting the ethernet cable from the switch and plug it in again, then also de Web Interface will working again,
best regards,
Hello Laurent,
ip management port works fine with firmware release 12.0.0.11!
But with this firmware version we have a warning every two seconds:
"DOT1S[dtlTask]: dot1s_txrx.c(269) 839 %% dot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU type"
That was the reason we switch from firmware version 12.0.0.11 to 12.0.2.9 (where above issue BPDU is fixed),
Is there are any respons about the tech support files I send?
best regards,
