Number of packets dropped because of tail drop.
Number of packets dropped because of random early detection (RED).
• (M Series and T Series routers only) On M320 and M120 routers and the T Series routers, the total
number of dropped packets is displayed. On all other M Series routers, the output classifies dropped
packets into the following categories:
• Low, non-TCP—Number of low-loss priority non-TCP packets dropped because of RED.
• Low, TCP—Number of low-loss priority TCP packets dropped because of RED.
• High, non-TCP—Number of high-loss priority non-TCP packets dropped because of RED.
• High, TCP—Number of high-loss priority TCP packets dropped because of RED.
• (J Series routers and MX Series routers with enhanced DPCs, and T Series routers with enhanced
FPCs only) The output classifies dropped packets into the following categories:
• Low—Number of low-loss priority packets dropped because of RED.
• Medium-low—Number of medium-low loss priority packets dropped because of RED.
• Medium-high—Number of medium-high loss priority packets dropped because of RED.
• High—Number of high-loss priority packets dropped because of RED.
Number of bytes dropped because of RED. The byte counts vary by PIC type. For more information,
see Table 19 on page 66.
• (M Series and T Series routers only) On M320 and M120 routers and the T Series routers, only the
total number of dropped bytes is displayed. On all other M Series routers, the output classifies
dropped bytes into the following categories:
• Low, non-TCP—Number of low-loss priority non-TCP bytes dropped because of RED.
• Low, TCP—Number of low-loss priority TCP bytes dropped because of RED.
• High, non-TCP—Number of high-loss priority non-TCP bytes dropped because of RED.
• High, TCP—Number of high-loss priority TCP bytes dropped because of RED.
• (J Series routers only) The output classifies dropped bytes into the following categories:
• Low—Number of low-loss priority bytes dropped because of RED.
• Medium-low—Number of medium-low loss priority bytes dropped because of RED.
• Medium-high—Number of medium-high loss priority bytes dropped because of RED.
• High—Number of high-loss priority bytes dropped because of RED.
Chapter 2: Common Interface Commands
Byte counts vary by PIC type. Table 19 on page 66 shows how the byte counts on the
outbound interfaces vary depending on the PIC type. Table 19 on page 66 is based on
the assumption that outbound interfaces are sending IP traffic with 478 bytes per packet.
