napalm-c2950

NAPALM driver for the Cisco Catalyst 2950 (WS-C2950G-48-EI) — a Layer-2-only switch running classic IOS 12.1(x)EA. The official napalm-ios driver assumes modern IOS syntax and features (e.g. show mac address-table, LLDP) that this platform predates or lacks, so this dedicated driver targets the old CLI.

• Transport: netmiko (device_type=cisco_ios)
• Base class: napalm.base.NetworkDriver

Install

pip install napalm-c2950

Usage

from napalm import get_network_driver

driver = get_network_driver("c2950")   # resolves to napalm_c2950.C2950Driver
with driver("192.0.2.10", "admin", "secret") as device:
    print(device.get_facts())
    print(device.get_vlans())

Supported getters

Everything else raises NotImplementedError.

¹ The 2950 does not report unicast counts or a TX multicast/broadcast split; those six fields are returned as -1. ² IOS reports ARP age in minutes; it is converted to seconds. vrf is accepted for API compatibility but ignored (single routing table). ³ Candidate config is not supported (candidate is always ""). sanitized=True uses NAPALM's CISCO_SANITIZE_FILTERS. full=True is accepted but ignored — this IOS has no show running-config all. ⁴ The disp column is mapped to jitter; type is not reported (empty string). ⁵ Only fan and power status are exposed by show env all; temperature/cpu are empty and memory fields are -1. ⁶ Not part of the NAPALM schema (there is no CDP getter). Provided as a private method because the 2950 has no LLDP; kept private so the NAPALM method-signature test still passes.

Tested firmware

• IOS 12.1(22)EA9 on WS-C2950G-48-EI

Notes

• The 2950 does not implement LLDP. get_lldp_neighbors_detail currently raises NotImplementedError; a CDP-based (show cdp neighbors detail) alternative can be added if desired, though it is not standard NAPALM LLDP semantics.
