Verify max-bindings value entered is in the range
Invalid input: <value>
If DHCPv6-Snooping is already configured before
entering the command and current bindings are
greater than the value being set.
Existing bindings %d are more than the max-
bindings being configured, and the maximum
limit will be applied once the number of existing
bindings fall below this limit
If the value is being configured for a trusted port
Cannot configure maximum binding for DHCPv6
snooping feature on a trusted port
If the value is being configured for a port which is
not a part of a dhcpv6-snooped vlan
Port %s is not a part of a DHCPv6-snooping
VLAN.
If the max-binding value is being set for a Dynamic
trunk.
Cannot configure DHCPv6 Snooping on a port
when Dynamic Trunking is enabled on that port.
If the number of static bindings is greater than the
max-binding value being set.
Cannot configure the maximum binding value
because the number of static bindings on the
port exceeds the maximum binding value.
If a port on which max-binding is enabled is being
put into a trunk.
Cannot add a port to a trunk group when
DHCPv6 Snooping Maxbinding is configured on
that port.
If a trunk has max-bindings configured on it. And the
trunk is being removed.
Cannot remove the port %s from the trunk group
because DHCPv6 Snooping max-binding is
configured on the trunk and removing the port
will delete the trunk.
If DT trunk is being configured on a max-binding
enabled port.
Cannot configure Distributed Trunking on a port
when DHCPv6 Snooping max-binding is
configured on that port.
IMPORTANT:
DT trunks can use jumbo VLAN as usual, but user needs to ensure that jumbo is
configured on both the DT pairs, otherwise packet drops/fragmentations can be seen.
