Cisco Switches Use Two Different Sets of Status Codes

Troubleshooting mainly consists of three things that are: Prediction of what can happen, determining anomalies, and investigating why the anomalies happen. Most of the network admins usually break down network infrastructure problems by the analysis of the layer path via the network, hop by hop, in the two directions. The process aids in the isolation of the problem; the moment they determine which hop in the path fails and thus make them venture into finer details concerning the same ADDIN ZOTERO_ITEM CSL_CITATION {"citationID":"muDGblsJ","properties":{"formattedCitation":"(Informational & Gundavelli, 2015)","plainCitation":"(Informational & Gundavelli, 2015)","noteIndex":0},"citationItems":[{"id":402,"uris":["http://zotero.org/users/9005746/items/4SNB938B"],"itemData":{"id":402,"type":"document","abstract":"Logical Interface Support for multi-mode IP Hosts draft-ietf-netext-logical-interface-support-10 A Logical Interface is a software semantic internal to the host operating system.

Show interface commands and interface status codes
Cisco switches incorporate the use of two different sets of status codes. These two sets of codes can be used for the determination of the working condition of the interface.
1 Show interface and show interface description
These types of commands provide a list of line status and protocol status. Most importantly shows if Layer 1 is working (line status) and whether Layer 2 is working(protocol status). For the LAN switch interfaces, these two codes typically have the same value either up or down.
2 Show interface status
