Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 503
If neither dynamic cost nor OSPF auto-cost is configured, the cost advertised is determined
by the cost configured on the OSPF metric, provided that the number of links that are up
exceeds the configured LAG threshold value; if the number of links that are up falls below the
threshold, the configured threshold action determines whether 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 of a LAG must match that of its member links. If the encapsulation
type of the LAG is changed, the encapsulation type of all its member links also changes.
The encapsulation type can be changed on the LAG only if there is no interface or service
associated with it. If the MTU is set to a non-default value, it will be reset to the default value
when the encapsulation type is changed.
The no form of this command reverts to the default encapsulation type.
Default null — all traffic on the link belongs to a single service or VLAN
Parameters dot1q — ingress Ethernet frames carry IEEE 802.1Q tags, each tag signifying a different
service
null — ingress Ethernet frames do not use any tags to indicate a service. As a result, only
one service can be configured on a link with null encapsulation.
qinq — ingress frames carry two tags, where the outer tag is the service provider tag and
the inner tag is the customer service tag as defined in 802.1ad
hold-time
Syntax hold-time down hold-down-time
no hold-time
Context config>lag
Description This command specifies the delay between detecting that a LAG is down (all active ports are
down) and reporting it to the upper layer protocols.
