packet-byte-offset
Syntax packet-byte-offset {add add-bytes | subtract sub-bytes}
no packet-byte-offset
Context config>service>vpls>sap>egress>hsmda-queue-over
config>service>vpls>sap>ingress>hsmda-queue-over
Description This command adds or subtracts the specified number of bytes to the accounting function for each
packet handled by the HSMDA queue. Normally, the accounting and leaky bucket functions are based
on the Ethernet DLC header, payload and the 4 byte CRC (everything except the preamble and inter-
frame gap). As an example, the packet-byte-offset command can be used to add the frame encapsula-
tion overhead (20 bytes) to the queues accounting functions.
The accounting functions affected include:
• Offered High Priority / In-Profile Octet Counter
• Offered Low Priority / Out-of-Profile Octet Counter
• Discarded High Priority / In-Profile Octet Counter
• Discarded Low Priority / Out-of-Profile Octet Counter
• Forwarded In-Profile Octet Counter
• Forwarded Out-of-Profile Octet Counter
• Peak Information Rate (PIR) Leaky Bucket Updates
