API Reference: VLAN Network Segmentation Agent
Overview
Configures and audits VLAN-based network segmentation on Cisco and multi-vendor switches using Netmiko and NAPALM. Creates VLANs, configures access/trunk ports, hardens unused ports, and audits for VLAN hopping vulnerabilities.
Dependencies
| Package | Version | Purpose |
|---|---|---|
| netmiko | >=4.0 | SSH-based switch configuration |
| napalm | >=4.0 | Multi-vendor network device management |
CLI Usage
# Audit VLAN configuration
python agent.py --host 192.168.1.1 --username admin --password pass --audit-only
# Full configuration mode
python agent.py --host 192.168.1.1 --username admin --password pass --device-type cisco_ios
Key Functions
connect_netmiko(host, username, password, device_type)
Establishes SSH connection via Netmiko supporting cisco_ios, cisco_nxos, arista_eos, juniper_junos.
get_vlan_config(conn)
Retrieves current VLAN configuration with TextFSM parsing of show vlan brief.
create_vlan(conn, vlan_id, vlan_name)
Creates a new VLAN with name on the switch.
configure_access_port(conn, interface, vlan_id)
Configures port as access with port-security, portfast, and BPDU guard.
configure_trunk_port(conn, interface, allowed_vlans)
Configures trunk port with explicit allowed VLANs, native VLAN 999, and DTP disabled.
harden_unused_ports(conn, interfaces)
Assigns unused ports to quarantine VLAN 999 and shuts them down.
configure_inter_vlan_acl(conn, acl_name, rules)
Creates extended ACLs for inter-VLAN routing access control.
audit_vlan_security(conn)
Checks for: default native VLAN, unhardened unused ports, and DTP negotiation enabled.
get_napalm_config(host, username, password, driver)
Retrieves device facts, interfaces, and VLANs using NAPALM for multi-vendor support.
Security Checks
| Check | Severity | Issue |
|---|---|---|
| Native VLAN | Medium | Default VLAN 1 on trunks enables VLAN hopping |
| Unused Ports | Low | Unhardened ports allow unauthorized network access |
| DTP Negotiation | High | Dynamic trunking enables VLAN hopping attacks |
| Port Security | Medium | Missing MAC address limiting |
Supported Device Types
Netmiko: cisco_ios, cisco_nxos, arista_eos, juniper_junos, hp_procurve
NAPALM: ios, nxos, eos, junos
