Likewise, in the following configuration, packets with dot1p priority 0–3 are marked as dot1p 7 in the outer tag and queued to
Queue 3. Rate policing is according to qos-policy-input 3. All other packets will have outer dot1p 0 and hence are queued
to Queue 1. They are therefore policed according to qos-policy-input 1.

Mapping C-Tag to S-Tag dot1p Values
To map C-Tag dot1p values to S-Tag dot1p values and mark the frames accordingly, use the following commands.
1. Allocate CAM space to enable queuing frames according to the C-Tag or the S-Tag.
CONFIGURATION mode
cam-acl l2acl number ipv4acl number ipv6acl number ipv4qos number l2qos number l2pt
number ipmacacl number {vman-qos | vman-qos-dual-fp} number
● vman-qos: mark the S-Tag dot1p and queue the frame according to the original C-Tag dot1p. This method requires half
as many CAM entries as vman-qos-dual-fp.
● vman-qos-dual-fp: mark the S-Tag dot1p and queue the frame according to the S-Tag dot1p. This method requires
twice as many CAM entries as vman-qos and FP blocks in multiples of 2.
The default is: 0 FP blocks for vman-qos and vman-qos-dual-fp.
2. The new CAM configuration is stored in NVRAM and takes effect only after a save and reload.
EXEC Privilege mode
copy running-config startup-config
3. Reload the system.

4. Map C-Tag dot1p values to a S-Tag dot1p value.
INTERFACE mode
vlan-stack dot1p-mapping c-tag-dot1p values sp-tag-dot1p value
Separate C-Tag values by commas. Dashed ranges are permitted.
Dynamic Mode CoS overrides any Layer 2 QoS configuration in case of conflicts.
