Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

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 ecfmacl 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 reload
3. 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.
