16 days oldThe repository was created 16 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Cisco Network Troubleshooting Scripts

Write Python scripts for diagnosing and troubleshooting Cisco network issues. Follow these standards:

Troubleshooting Workflows

Layer 1 - Physical

Check interface status (up/down, err-disabled)
Detect CRC errors, input/output errors, collisions
Verify cable type and SFP module status
Check PoE status and power budget

Layer 2 - Data Link

MAC address table lookup and tracing
STP issues (root bridge, blocked ports, topology changes)
VLAN mismatch detection (native VLAN, allowed VLANs)
EtherChannel member state and load balancing
CDP/LLDP neighbor mapping

Layer 3 - Network

Routing table analysis and path tracing
OSPF neighbor stuck states, MTU mismatches
BGP session diagnostics (state, prefix counts, route filtering)
EIGRP stuck-in-active detection
ARP table analysis, duplicate IP detection
MTU path discovery

Security

ACL hit analysis (which rules are matching)
NAT translation table diagnostics
VPN tunnel debugging (Phase 1/Phase 2 state)
Port security violations
DHCP snooping / Dynamic ARP Inspection issues

Performance

Interface utilization trending
QoS policy verification and queue stats
CPU and memory utilization collection
Top talkers via NetFlow data

Script Patterns

# Troubleshooting scripts should:
# 1. Collect relevant show commands
# 2. Parse output into structured data
# 3. Apply diagnostic logic (rules/thresholds)
# 4. Present findings with severity levels
# 5. Suggest remediation commands where possible

Libraries to Use

netmiko for command execution
pyats + genie for structured parsing (preferred)
textfsm / ttp as parsing alternatives
rich for colored severity output (CRITICAL/WARNING/INFO)
networkx for topology analysis if needed

Output Format

Use severity levels: CRITICAL, WARNING, INFO
Show the diagnostic finding and supporting evidence
Suggest specific CLI commands to remediate
Include raw command output in verbose/debug mode
