15.3. 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:

The remark-type of the policy also determines the values the user can configure in the policy and also the QoS policy with which this remark policy can be associated. Table 48 lists the remark policies supported on the node and their use.

This command specifies the forwarding class name and enables 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 specifies the marking of the DEI bit for fc fc-name according to the in and out of profile status of the packet (fc-name may be used to identify the dot1p-value).

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

In the PBB case, for a backbone SAP (B-SAP) and for packets originated from a local I-VPLS, the command determines the marking of the DEI bit for both the BVID and ITAG.

If this command is not used, the DEI bit should be preserved if an ingress TAG exists or set to zero otherwise.

A de-value that is specifically mentioned in the command line means this value is used for all the packets of this FC, regardless of their in or out of profile status.

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.

DEI marking must be enabled using the de-mark command along with this command for the command to take effect. When the de-mark command is configured along with this command, the DEI bit is marked in the packet to indicate the profile of the packet. The DEI bit is marked to 0 to indicate an in-profile/green packet and 1 to indicate an out-of-profile/yellow packet. If the de-value parameter is specified, the DEI bit is set to the value specified for all packets.

The no form of this command specifies that the software uses the dot1p-in-profile and dot1p-out-profile, if configured, otherwise the software uses the default values.

This command marks on egress the in- and out-of-profile status using a particular dot1p combination, in a similar manner as the DEI options. Use this command when the internal in- and out-of-profile status must be communicated to an adjacent network or customer device that does not support the DEI bit.

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) for 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 DEI marking is enabled using the de-mark command and the dot1p dot1p-value command is used to configure the dot1p value, this command has no effect. This means that enabling DEI marking has precedence over this command and the system ignores this command.

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 related DEI bit is set to 0.

When the dot1p dot1p-value command is used and de-mark is enabled, the dot1p-value is used for the entire forwarding class. This command is mutually exclusive to the use of the dot1p command.

The no form of this command reverts the IEEE 802.1p or IEEE 802.1q priority bits to the default.

The command marks on egress the in- and out-of-profile status using a particular dot1p combination, in a similar manner as the DEI options. Use this command when the internal in- and out-of-profile status must be communicated to an adjacent network or customer device that does not support the DEI bit.

This command explicitly defines the egress IEEE 802.1p (dot1p) bits marking for fc-name. When the marking is set, all packets with out-of-profile status (or yellow color) 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 DEI marking is enabled using the de-mark command and the dot1p-value is configured, this command has no effect. This means that enabling DEI marking has precedence over this command and the system ignores this command.

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 related DEI bit is set to 0.

When the dot1p dot1p-value command is used and de-mark is enabled, the dot1p value is used for the entire FC. This command is mutually exclusive to the use of the dot1p dot1p-value command.

The no form of this command reverts the IEEE 802.1p or IEEE 802.1q priority bits to the default.

The command marks on egress the in- and out-of-profile status using a particular dot1p combination. Use this command 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 explicitly defines the egress dot1p bits marking for fc-name. When the marking is set, all packets with in-profile status (green color) for fc-name that egress out of QinQ SAP (for example, SAPs configured with two VLAN tags explicitly defined, such as SAP 1/1/5:10.100) only use the explicitly defined in-profile and out-profile dot1p-value.

This command has no effect for egress packets sent out of all other non-QinQ SAPs, such as 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. This command takes effect only when the node adds two tags to the packet on egress.

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

The no form of this command specifies that default remarking values are used for marking the inner VLAN.

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

When multiple DSCP names are associated with the FC in the policy, the last name entered overwrites 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 FC. When marking is set, the corresponding DSCP value is used to mark all IP packets with out-of-profile status, on egress of this FC queue.

When multiple DSCP names are associated with the FC in the policy, the last name entered overwrites the previous value.

The no form of this command reverts to the default out-of-profile dscp-name value for policy ID 1.

This command specifies the in-profile LSP EXP value for the FC. The EXP value is used for all LSP labeled packets that require marking on egress for this FC queue that are in-profile.

When multiple EXP values are associated with the FC at network egress, the last name entered overwrites the previous value.

The no form of this command reverts to the default value.

This command specifies the out-of-profile LSP EXP value for the FC. The EXP value is used for all LSP labeled packets that require marking on egress for this FC queue that are out-of-profile.

When multiple EXP values are associated with the FC at network egress, the last name entered overwrites the previous value.

The no form of this command reverts to the default out-of-profile value.

This command specifies the in-profile dot1p LSP EXP value for the FC. This value is used for all in-profile LSP labeled packets that require marking on egress for the FC queue.

When multiple dot1p LSP EXP values are associated with the FC at network egress, the last name entered overwrites the previous value.

The no form of this command reverts to the default in-profile dot1p LSP EXP value.

This command specifies the in-profile dot1p LSP EXP value for the forwarding class. This value is used for all out-of-profile LSP labeled packets which require marking the egress on the forwarding class queue.

When multiple dot1p LSP EXP values are associated with the forwarding class at network egress, the last name entered overwrites the previous value.

The no form of this command reverts to the default in-profile dot1p LSP EXP value.
