13.4. Remark Policy Command Reference

This command creates a text description stored in the configuration file for a configuration context.

The description command associates a text string with a configuration context to help identify the context in the configuration file.

The no form of this command removes any description string from the context.

This command creates a new remark policy of the specified type.

The following types of remark policies are available on the 7210 SAS-K 2F1C2T:

The following type of remark policies are available on the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C:

The remarking-type of the policy also determines the values user is allowed to configure in the policy and the QoS policy with which this policy can be associated with. See the Summary of Remark Policy and Attachment Points for 7210 SAS-K 2F1C2Tfor the different remark policies supported on the node and its use.

Note: A limited number of unique remark policies are available to be shared among all the different types of remark policies. The remark policy types share the available resources, and scaling one type of remark policy reduces the number of policies allowed for other types of remark policies.

This command specifies the forwarding class name and provides the context to configure the marking value for the FC. Based on the type of remark policy created, the fc command allows the user to specify the appropriate marking values. The fc command overrides the default parameters for the forwarding class to the values defined.

The no form of this command removes the forwarding class to marking values map associated with the FC. The forwarding class reverts to the defined parameters in the default remark policy.

This command explicitly defines the marking of the DEI bit of the outermost tag for fc fc-name according to the in and out of profile status of the packet.

If no de-value is present, the default values are used for the marking of the DE bit, as defined in the IEEE 802.1ad-2005 standard. For example, 0 for in-profile packets, 1 for out-of-profile ones

If the de-value is specifically mentioned in the command line it means this value is to be used for all the packets of this forwarding class regardless of their in or out of profile status.

Note: If remarking is enabled, the inner tag DEI is always set to zero irrespective of de-mark-outer. If remarking is enabled and de-mark-outer is not configured then, DEI bit of the outer tag is set to zero. If remarking is disabled then, the DEI bits are preserved for both inner and outer tag.

This command explicitly defines the egress IEEE 802.1P (dot1p) bits for the inner VLAN tag marking for fc-name. When the marking is set, all packets of fc-name that egresses out of QinQ SAP only (that is, SAPs configured with two VLAN tags explicitly defined; for example, SAP 1/1/5:10.100) use the explicitly defined dot1p-value.

This command has no effect for egress packets sent out of all other non-QinQ SAPs; for example, Dot1q SAP and NULL SAP. Additionally, if the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P encapsulated, this command has no effect. In other words, this command takes effect, only when the node adds 2 tags to the packet on the egress.

If the no form of this command is executed, the default remarking values are used.

This command explicitly defines the egress IEEE 802.1P (dot1p) bits marking for fc-name. When the marking is set, all packets with in-profile status (or green color) of fc-name that egress out of QinQ SAP only (that is, SAPs configured with two VLAN tags explicitly defined; for example, SAP 1/1/5:10.100) use the explicitly defined in-profile and out-profile dot1p-value.

This command adds the capability to mark the in and out profile status on an egress through a certain dot1p combination. It may be used when the internal in and out of profile status needs to be communicated to an adjacent network or customer device that does not support the DEI bit.

This command has no effect for egress packets sent out of all other non-QinQ SAPs; for example, Dot1q SAP and NULL SAP. Additionally, if the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P encapsulated, this command has no effect. In other words, this command takes effect, only when the node adds 2 tags to the packet on the egress.

This variant of the command is mutually exclusive to the use of the dot1p-inner command. In other words, user has a choice to use either this command or the dot1p-inner command but not both together.

If the no form of this command is executed, default remarking values are used for marking the inner VLAN.

This command explicitly defines the egress IEEE 802.1P (dot1p) bits marking for fc-name. When the marking is set, all packets of fc-name that have either an IEEE 802.1Q or IEEE 802.1P encapsulation use the explicitly defined dot1p-value. If the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P encapsulated, the dot1p command has no effect.

If the no form of this command is executed then software will use the default value.

This command specifies the in-profile DSCP name for the forwarding class. When marking is set, the corresponding DSCP value is used to mark all IP packets with in-profile status, on the egress of this forwarding class queue.

When multiple DSCP names are associated with the forwarding class in the policy, the last name entered will overwrite the previous value.

The no form of this command reverts to the factory default in-profile dscp-name setting for policy ID 1.

This command specifies the out-of-profile DSCP name for the forwarding class. When marking is set, the corresponding DSCP value is used to mark all IP packets with out-of-profile status, on the egress of this forwarding class queue.

When multiple DSCP names are associated with the forwarding class in the policy, the last name entered will overwrite the previous value.

The no form of this command reverts to the factory default out-of-profile dscp-name setting for policy-id 1.

This command explicitly defines the egress IEEE 802.1P (dot1p) bits marking for fc-name. When the marking is set, all packets with in-profile status (or green color) of fc-name that have either an IEEE 802.1Q or IEEE 802.1P encapsulation use the explicitly defined in-profile dot1p-value. Similarly all the packet with out-of-profile status use the explicitly defined out-profile dot1p-value. If the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P encapsulated, this command has no effect.

This command adds the capability to mark on an egress the in and out profile status via a certain dot1p combination, similarly with the DEI options. It may be used when the internal in and out of profile status needs to be communicated to an adjacent network or customer device that does not support the DEI bit.

When this command is used the DEI Bit is left unchanged by the egress processing if a tag exists. If a new tag is added, the DEI bit is set to 0.

This variant of the command is mutually exclusive to the use of the dot1p-outer command. In other words, user has a choice to use either this command or the dot1p-outer command but not both together.

If the no form of this command is executed then the default remark values are used.

This command specifies the in-profile MPLS EXP value for the forwarding class. When marking is set, the corresponding MPSL EXP value is used to mark all MPLS packets with in-profile status, on the egress of this forwarding class queue.

When multiple MPLS EXP names are associated with the forwarding class in the policy, the last name entered will overwrite the previous value.

The no form of this command reverts to the factory default in-profile MPLS EXP value setting for policy-id 1.

This command specifies the out-of-profile MPLS EXP value for the forwarding class. When marking is set, the corresponding MPSL EXP value is used to mark all MPLS packets with out-of-profile status, on the egress of this forwarding class queue.

When multiple MPLS EXP names are associated with the forwarding class in the policy, the last name entered will overwrite the previous value.

The no form of this command reverts to the factory default out-profile MPLS EXP value setting for policy ID 1.
