I can telnet but I have created many vlans when i put vr vr-vlanblue it shows invalid.
Telnet can only be access by default and mgmt vlan..

Thank you!

By default, the switch will send telnet through VR-Mgmt (Mgmt port). If the telnet have to use VR-Default (all ports except Mgmt port) then you have to add VR-Default to the telnet command.

If you are using User-Created VRs (not VR-Default/VR-Mgmt) you have to add the to the telnet command as already mentioned before.

You can use show vlan command to check which VR is associated with which vlan.

Also, by default, ping is sent through VR-Default instead of VR-Mgmt.
