IPv6 Support for TPVM

TPVM supports configuring its management interfaces and various other services such as NTP, DNS, LDAP, etc. using IPv6.

The following commands now support configuring using IPv6.

• ntp
• dns
• interface management
• tpvm upgrade
• trusted-peer
• tpvm download
• ldap ca-cert
• ldap host

Downgrading TPVM to a lower version when IPv6 is configured

Care should be taken to remove the IPv6 configuration before downgrading to a lower TPVM version. Any configuration that uses IPv6 must be removed and reconfigured using IPv4.

When downgrading from SLX-OS 20.4.3 to SLX-OS 20.4.2, ensure that the IPv6 LDAP configurations are reset to using IPv4 before starting the downgrade. When downgrading to SLX-OS 20.4.1, ensure that any IPv6 configuration is reset to using IPv4 before starting the downgrade.

When downgrading from SLX-OS 20.4.3 to SLX-OS 20.3.x or below, ensure that no IPv6 configuration is present. All TPVM configurations must use IPv4 only.
