The value of tmnxMcsDhcpsSyncTag specifies a synchronization tag
to be used while synchronizing this DHCP Server with the multi-chassis
peer.
The value of tmnxMcsDhcpsSyncTag must be set simultaneously with
the value of tmnxMcsDhcpsPeerIpAddr and the value of
tmnxMcsDhcpsPeerIpType.
When the value of tmnxMcsDhcpsRowStatus is set to 'createAndGo', the
value of tmnxMcsDhcpsSyncTag must be set, too.
Modifying the value of tmnxMcsDhcpsSyncTag while the value of
tmnxMcsDhcpsRowStatus is equal to 'active', is only alllowed while
the value of TIMETRA-DHCP-SERVER-MIB::tmnxDhcpsFoState for this
DHCP Server is equal to 'partnerDown (5)'.
