LAG Commands
If dynamic cost is not configured and OSPF autocost is configured, then costing is applied based on the total
number of links configured. This cost will remain static provided the number of links that are up exceeds the
configured LAG threshold value at which time the configured threshold action determines if and at what
cost this LAG will be advertised.
If dynamic-cost is configured and OSPF autocost is not configured, the cost is determined by the cost
configured on the OSPF metric provided the number of links available exceeds the configured LAG
threshold value at which time the configured threshold action determines if this LAG will be advertised.
If neither dynamic-cost nor OSPF autocost are configured, the cost advertised is determined by the cost
configured on the OSPF metric provided the number of links available exceeds the configured LAG
threshold value at which time the configured threshold action determines if this LAG will be advertised.
The no form of this command removes dynamic costing from the LAG.
Default
no dynamic-cost
encap-type
Syntax
encap-type {dot1q | null | qinq}
no encap-type
Context
config>lag
Description
This command configures the encapsulation method used to distinguish customer traffic on a LAG. The
encapsulation type is configurable on a LAG port. The LAG port and the port member encapsulation types
must match when adding a port member.
If the encapsulation type of the LAG port is changed, the encapsulation type on all the port members will
also change. The encapsulation type can be changed on the LAG port only if there is no interface associated
with it. If the MTU is set to a non default value, it will be reset to the default value when the encap type is
changed.
The no form of this command restores the default.
Default
null — All traffic on the port belongs to a single service or VLAN.
Parameters
dot1q — Ingress frames carry 802.1Q tags where each tag signifies a different service.
null — Ingress frames will not use any tags to delineate a service. As a result, only one service can be
configured on a port with a null encapsulation type.
qinq — Specifies QinQ encapsulation.
