Description
Egress Pri3 Rate
Egress data rate limit for priority 3 frames.
Output traffic from this priority queue is shaped according to
the egress rate selected as shown below:
0000 = Not limited (Default)
0001 = 64 Kbps
0010 = 128 Kbps
0011 = 256 Kbps
0100 = 512 Kbps
0101 = 1 Mbps
0110 = 2 Mbps
0111 = 4 Mbps
1000 = 8 Mbps
1001 = 16 Mbps
1010 = 32 Mbps
1011 = 48 Mbps
1100 = 64 Mbps
1101 = 72 Mbps
1110 = 80 Mbps
1111 = 88 Mbps
Note: For 10Base-T, rate settings above 10Mbps are set to
the default value 0000 (Not limited).
Note: When multiple queue select enable is off (only 1
queue per port), rate limiting applies only to priority 0 queue.
Egress Pri2 Rate
Egress data rate limit for priority 2 frames.
Output traffic from this priority queue is shaped according to
the egress rate selected as shown below:
0000 = Not limited (Default)
0001 = 64 Kbps
0010 = 128 Kbps
0011 = 256 Kbps
0100 = 512 Kbps
0101 = 1 Mbps
0110 = 2 Mbps
0111 = 4 Mbps
1000 = 8 Mbps
1001 = 16 Mbps
1010 = 32 Mbps
1011 = 48 Mbps
1100 = 64 Mbps
1101 = 72 Mbps
1110 = 80 Mbps
1111 = 88 Mbps
