Layer 3/4 Priority Settings
– 250 –
the other bits for various application types. The ToS bits are defined in Table 18.
Command Usage
◆ Enter per-hop behavior and drop precedence for any of the IP Precedence
values 0 - 7.
◆ If the priority mapping mode is set the IP Precedence and the ingress packet
type is IPv4, then the IP Precedence-to-PHB/Drop Precedence mapping table is
used to generate priority and drop precedence values for internal processing.
◆ Random Early Detection starts dropping yellow and red packets when the
buffer fills up to 0x60 packets, and then starts dropping any packets regardless
of color when the buffer fills up to 0x80 packets.
Parameters
These parameters are displayed in the web interface:
◆ Interface – Specifies a port or trunk.
◆ IP Precedence – IP Precedence value in ingress packets.
(Range: 0-7)
◆ PHB – Per-hop behavior, or the priority used for this router hop. (Range: 0-7)
◆ Drop Precedence – Drop precedence used for Random Early Detection in
controlling traffic congestion. (Range: 0 - Green, 3 - Yellow, 1 - Red)
