What is runt and giant?
A giant frame is any frame whose size exceeds the maximum transmission unit (MTU). In ethernet thats larger than 1500bytes (not including the18 bytes for the Ethernet header and FCS). A runt is a frame that is smaller than the minimum frame size for IEEE-802.3 standard frames.
What are giants on a Cisco switch?
Number of received giant frames (frames that exceed the maximum IEEE 802.3 frame size) on the port. For example, any Ethernet packet that is greater than 1518 bytes is considered a giant.
What causes Ethernet Giants?
Giants – Ethernet frames that are longer than the maximum allowed length are called giants. Giants are caused by the same issues as those that cause runts….Configure Switch Ports.

|---|---|
| Error Type | Description |
| Late Collisions | A collison that occurs after 512 bits of the frame have been transmitted. |
What are interface throttles?
throttles: When the interface fails to buffer the incoming packet then this is considered a throttle. input errors: This counter will increase when the interface receives a frame with any kind of error, this includes runts, giants, no buffer available, CRC errors, etc.
What is a Cisco runt?
Runt packets are packets that are less than the minimum packet size (64 bytes for Ethernet). They often occur due to collisions on the line. On switches the cause is usually a mis-matched duplex problem (full on one end and half on the other) caused by bad autodetection of a device.
What causes runt packets?
Runt Frame In a half-duplex Ethernet environment, runt frames are almost always caused by collisions. If runt frames occur when collisions are not high or in a full-duplex Ethernet environment, then they are probably the result of under runs or bad software on a network interface card.
What is runt frame?
Runt Frame An Ethernet frame that is less than the minimum length of 64 bytes with bad FCS (whereas undersize frames < 64 bytes with good FCS). In a half-duplex Ethernet environment, runt frames are almost always caused by collisions.
What is Runt Cisco?
What is ARPA in CCNA?
The standard Advanced Research Projects Agency (ARPA) Ethernet Version 2.0 encapsulation, which uses a 16-bit protocol type code (the default encapsulation method).
Do you show ip interface brief?
IOS command #2: Show IP interface brief The show IP interface brief command gives you the answers to these questions and is the best summary of the status, protocol and IP addresses of your interfaces. This command can be used in both User EXEC and Privileged EXEC mode. This command can be abbreviated sh ip int brie.
What are runts on a switch?
Runts are Ethernet packets that are less than 64 bytes and may be caused by excessive collisions.
What is giant networking?
In networks, a giant is a packet , frame , cell, or other transmission unit that is too large. Network protocols specify maximum and minimum sizes (and sometimes a single uniform size) for any transmission unit. For example, ATM packages all data into 53-byte cells.
