7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command configures the minimum time in seconds an ARP entry learned on the IP interface will be stored in the ARP table. ARP entries are automatically refreshed when an ARP request or gratuitous ARP is seen from an IP host; otherwise, the ARP entry is aged from the ARP table. If arp-timeout is set to a value of zero seconds, ARP aging is disabled.
The no form of this command reverts to the default value.
14400 seconds
Specifies the minimum number of seconds a learned ARP entry will be stored in the ARP table, expressed as a decimal integer. A value of zero specifies that the timer is inoperative and learned ARP entries will not be aged.
delayed-enable seconds [init-only]
no delayed-enable
config>service>vprn>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command delays making an interface operational by the specified number of seconds.
In environments with many subscribers, it can take time to synchronize the subscriber state between peers when the subscriber-interface is enabled (for example, after a reboot). To ensure that the state has time to be synchronized, the delayed-enable timer can be specified. The optional init-only parameter can be added to use this timer only after a reboot.
no delayed-enable
Specifies the number of seconds to delay before the interface is operational.
Keyword that delays the initialization of the subscriber-interface to give the rest of the system time to complete necessary tasks, such as allowing routing protocols to converge or allowing MCS to sync the subscriber information. The delay occurs only immediately after a reboot.
vpls service-name
config>service
config>service>vprn>if
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command, within the IP interface context, binds the IP interface to the specified service name.
The system does not attempt to resolve the service name provided until the IP interface is placed into the administratively up state (no shutdown). When the IP interface is administratively up, the system scans the available VPLS services that have the allow-ip-int-binding flag set for a VPLS service associated with the name. If the service name is bound to the service name when the IP interface is already in the administratively up state, the system immediately attempts to resolve the specific name.
If a VPLS service is found associated with the name and the allow-ip-int-binding flag is set, the IP interface will be attached to the VPLS service, which allows routing to and from the service virtual ports when the IP interface is operational.
A VPLS service associated with the specified name that does not have the allow-ip-int-binding flag set or a non-VPLS service associated with the name will be ignored and will not be attached to the IP interface.
If the service name is applied to a VPLS service after the service name is bound to an IP interface and the VPLS service allow-ip-int-binding flag is set at the time the name is applied, the VPLS service is automatically resolved to the IP interface if the interface is administratively up or when the interface is placed in the administratively up state.
If the service name is applied to a VPLS service without the allow-ip-int-binding flag set, the system does not attempt to resolve the applied service name to an existing IP interface bound to the name. To rectify this condition, the flag must first be set and then the IP interface must enter or reenter the administratively up state.
While the specified service name may be assigned to only one service context in the system, it is possible to bind the same service name to more than one IP interface. If two or more IP interfaces are bound to the same service name, the first IP interface to enter the administratively up state (if currently administratively down) or to reenter the administratively up state (if currently administratively up) when a VPLS service is configured with the name and has the allow-ip-int-binding flag set will be attached to the VPLS service. Only one IP interface is allowed to attach to a VPLS service context. No error is generated for the remaining non-attached IP interfaces using the service name.
When an IP interface is attached to a VPLS service, the name associated with the service cannot be removed or changed until the IP interface name binding is removed. Also, the allow-ip-int-binding flag cannot be removed until the attached IP interface is unbound from the service name. Unbinding the service name from the IP interface causes the IP interface to detach from the VPLS service context. The IP interface may then be bound to another service name or a SAP or SDP binding may be created for the interface using the SAP or spoke-SDP commands on the interface.
Specifies the service name that the system will attempt to resolve to an allow-ip-int-binding enabled VPLS service associated with the name. This parameter is required when using the IP interface VPLS command. The specified name is expressed as an ASCII string comprised of up to 32 characters. It does not need to already be associated with a service, and the system does not check to ensure that multiple IP interfaces are not bound to the same name.
ingress
config>service>vprn>if>vpls
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command within the VPLS binding context defines the routed IP filter ID optional filter overrides.
v4-routed-override-filter ip-filter-id
no v4-routed-override-filter
config>service>ies>if>vprn>ingress
7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C
This command specifies an IP filter ID that is applied to all ingress packets entering the VPLS service. The filter overrides the existing ingress IP filter applied to SAPs or SDP bindings for packets associated with the routing IP interface. The override filter is optional and, if not defined or removed, the IP routed packets use the existing ingress IP filter on the VPLS virtual port.
The no form of this command removes the IP routed override filter from the ingress IP interface. When removed, the IP ingress routed packets within a VPLS service attached to the IP interface use the IP ingress filter applied to the packet virtual port, when defined.
Specifies the ID for the IP filter policy. Allowed values are integers that correspond to a previously created IP filter policy in the configure>filter>ip-filter context.
