GUI does not support segregated IPv6 addresses while creating CIFS shares using the Enterprise Vault policy
If you create CIFS share from the GUI using the Enterprise Vault policy, and you provide a virtual IP for IPv6, then it displays the IP as sharename@ipv6, which is not supported by Access Appliance.
Workaround:
Do not use virtual IPs when you create the CIFS share using the Enterprise Vault policy.
