Identify Network Bugs

Network bug identifier tool overview

The Catalyst Center network bug identifier tool allows you to scan the network for a selected set of defects or bugs that have been identified previously and are known to Cisco.

The Catalyst Center network bug identifier helps in identifying specific patterns in the device configuration or in the operational data of the device and matches them with known defects based on those patterns. This tool provides both bug-focused and device-focused views.

Catalyst Center collects network device configuration and operational data by running CLI commands on network devices, and then sends the information to the CX Cloud to be processed for exposure to potential security advisories or bugs. Catalyst Center invokes these CLI commands for the network bug identifier tool:

  • show buffers summary

  • show cef interfaces

  • show clock

  • show crypto eli all

  • show crypto isakmp sa detail

  • show eigrp service-family ipv4 neighbors

  • show environment all

  • show interfaces counters error

  • show interfaces summary

  • show inventory

  • show ip interface brief

  • show ip nat translations verbose

  • show ip nbar protocol-discovery

  • show ip nbar resources flow

  • show ip nhrp

  • show ip nhrp summary

  • show ip route

  • show ip ssh

  • show ip vrf

  • show logging

  • show performance monitor cache detail

  • show platform software route-map fp active map

  • show pnp profile

  • show redundancy

  • show redundancy application group

  • show running-config all

  • show scp status
