IPv6 address on VLAN error

[Sumanta_Ghosh]

Getting error while trying to assign IPv6 interface to a vlan. IPv6 forwarding is already enabled on the VLAN, along with port tagging.

Getting error as below:-

%% Invalid input detected at '^' marker.
%% A number within the range of 1-4094 is expected.

Hi All

Thanks for all your support. I still don't know why it didn't let me assign IPv6 address directly. I tried multiple times, but unless I mentioned eui64 fe80::/64, it kept on giving same error.

Not sure if it is SSH terminal related issue, since I logged in via multiple nodes into the switch. Maybe something related to character recognition.

This happened in both primary as well secondary switches. However, I'll again try to assign new IPv6 address after removing the eui64 fe80::/64 part and update this thread.

Cheers,
Sumanta.

If the secondary switch was also logined through multiple nodes, I would suggest to test first after connecting switch directly, not through multiple nodes. It would help to narrow down if the issue was caused by the character recognition and it would be the most simple way to test I think.

Hi,

At the beginning of the thread, you were having two issues:

1) you were trying to configure a vlan that was not present (the error message was requesting a vlan id)
2) the ipv6 address format was wrong

for example, I have the same error message below, vlan "myvlan" doesn't exist on the switch.

sw1.3 # configure vlan myvlan ipaddress fd01:976a:c200:6f1b:0:0:1::2/127
%% Invalid input detected at '^' marker.
%% A number within the range of 1-4094 is expected.
As for the IPv6 address, I'd not recommend the use of /127. For links, stay with /64, it's better that way.

Hi Sumanta,

Well, today I tested it on same model (x770-32q) and same version 21.1.2.14 but it worked well as below:

The configuration was applied without any error and also without eui64 configuration.
I guess there was some problem at the time when you were executing the config.
