10 Network Management
Device Discovery & Topology
Protocols: CDP (Cisco proprietary)
Protocols: LLDP (vendor-neutral)
Commands: show cdp neighbors, show lldp neighbors detail
Building and documenting network topology
Performance Metrics & Trends
Latency, throughput, packet loss, jitter
Interface utilization, errors, discards
Traffic patterns, peak vs off-peak
Capacity planning
Security & Trust Boundaries in Management
Managing access to SNMP (v3 vs v1/v2)
Trust boundaries for traffic marking also relevant in management domain
Ensuring that management traffic itself is reliable and secure
Monitoring Tools & Protocols
SNMP (Simple Network Management Protocol) – versions, authentication, encryption
Log messages / Syslog: capturing events, timestamps
Network baseline: establishing normal performance metrics and comparing current state
Configuration Management & Backup
Backing up device configurations (TFTP, USB, etc)
Version control, change control
Validating configurations
Fault Managament / Trouble Detection
Alerts and events when performance deviates from baseline
Using topology discovery + monitoring to locate issues
Using commands like show cdp neighbours, checking MIBs for issues
