The display interface brief and display interface commands display different interface bandwidth usage. Why

14

The display interface brief and display interface commands should display the same interface bandwidth usage. By default, the interval for traffic statistics on an interface is 300s. Within the first 300s, the statistics are instable. Wait for 300s and check the statistics, or run the set flow-stat interval command to change the interval for traffic statistics.

You can run the display interface command to view the maximum bandwidth of an interface ( Max-bandwidth) and the rate of packets received or sent in the last 3000 seconds (Last 300 seconds input rate/Last 300 seconds output rate).

Different MTUs are displayed in the display isis interface command output on an S series switch
Q: In the display isis interface command output, why is the MTU on a broadcast network 1497 bytes whereas the MTU on a P2P network 1500 bytes? A: By default, the physical MTU of Ethernet interfaces are 1500 bytes. On a P2P network that has PPP enabled, the MTU is 1500 bytes in the display isis interface command output. On a broadcast network, a 3-byte Local Link Control (LLC) field is added to the data field according to the 802.3 link protocol encapsulation format, and the value of the LLC field is FEFE03. Therefore, in IS-IS, the actual length of the data to be transmitted is 1497 bytes, which is 3 bytes shorter than the physical MTU.
