What causes transmit discards Cisco?

What causes transmit discards Cisco?

Transmit Discards indicate that packets were not transmitted because of network congestion. It can’t handle any more packets, so the switch tries to queue them up. Once the queues/buffers are full, the packets are discarded.

What causes router discards?

A typical cause of discards is when the router needs to regain some buffer space. In the case of discards, the issue is almost always with the router that’s reporting the discards (not witha a next hop device, bad cable, etc).

Why does a switch discard packets?

A packet discard happens when a received packet has a transmission or format error, or when the receiving device doesn’t have enough storage room for it. While some discarding is inevitable, excessive discards can point to several problems including: A network device is misconfigured.

What is Interface output discards?

“output discard” is a packet that passed through the fabrinc interface, but was dropped because the host-interface (HIF) buffers are full.

What causes high discards on an interface?

An interface discard is where the device has decided to discard a packet for some reason. It could be a corrupt packet, the device is busy, buffer overflows, packet size issues, and several other things.

How do you troubleshoot interface discards?

Troubleshooting Discards

  1. Verify VLAN configurations on ports and switches experiencing the discards. It is important to make sure the port is in the correct mode (trunk or access).
  2. Check the Spanning-Tree Topology.
  3. Check the interface bandwidth to see if its possibly overbooked.
