Description
Egress Pri1 Rate
Egress data rate limit for priority 1 frames.
Output traffic from this priority queue is shaped according to the egress rate selected
below:
0000 = Not limited (default)
0001 = 64Kbps
0010 = 128Kbps
0011 = 256Kbps
0100 = 512Kbps
0101 = 1Mbps
0110 = 2Mbps
0111 = 4Mbps
1000 = 8Mbps
1001 = 16Mbps
1010 = 32Mbps
1011 = 48Mbps
1100 = 64 Mbps
1101 = 72Mbps
1110 = 80Mbps
1111 = 88Mbps
Notes: For 10BT, rate settings above 10Mbps are set to the default value 0000 (not
limited).
When multiple queue select enable is off (only 1 queue per port), rate limiting applies
only to priority 0 queue.
Egress Pri0 Rate
Egress data rate limit for priority 0 frames.
Output traffic from this priority queue is shaped according to the egress rate selected
below:
0000 = Not limited (default)
0001 = 64Kbps
0010 = 128Kbps
0011 = 256Kbps
0100 = 512Kbps
0101 = 1Mbps
0110 = 2Mbps
0111 = 4Mbps
1000 = 8Mbps
1001 = 16Mbps
1010 = 32Mbps
1011 = 48Mbps
1100 = 64 Mbps
1101 = 72Mbps
1110 = 80Mbps
1111 = 88Mbps
Notes: For 10BT, rate settings above 10Mbps are set to the default value 0000 (not
limited).
When multiple queue select enable is off (only 1 queue per port), rate limiting applies
only to priority 0 queue.
