Capabilities¶

Every NAPALM method the driver supports, at a glance. All state getters read from the SR Linux state datastore over JSON-RPC — structured data straight from the device, no screen scraping. Click through for per-method details and real example output.

State getters¶

method	returns
`get_facts()`	hostname, model, serial, OS version, uptime, interface list
`get_environment()`	fans, power supplies, temperature, CPU, memory
`get_users()`	local users with hashed passwords and SSH keys
`get_snmp_information()`	SNMP contact/location
`get_ntp_servers()`	configured NTP servers
`get_ntp_stats()`	NTP synchronization state
`is_alive()`	JSON-RPC endpoint reachability
`get_interfaces()`	state, speed, MTU, MAC per interface
`get_interfaces_counters()`	octet/packet/error counters per subinterface
`get_interfaces_ip()`	IPv4/IPv6 addresses per subinterface
`get_optics()`	transceiver TX/RX power, laser bias
`get_lldp_neighbors()`	LLDP neighbor summary
`get_lldp_neighbors_detail()`	full LLDP TLVs per neighbor
`get_vlans()`	VLANs derived from mac-vrf bridged subinterfaces
`get_mac_address_table()`	learned MAC addresses in mac-vrfs
`get_bgp_neighbors()`	BGP sessions per network-instance
`get_bgp_neighbors_detail()`	timers, message counters, session details
`get_bgp_config()`	BGP groups and neighbors as configured
`get_route_to()`	RIB lookup with protocol attributes
`get_arp_table()`	IPv4 ARP entries
`get_ipv6_neighbors_table()`	IPv6 neighbor discovery entries
`get_network_instances()`	network-instances (VRFs) and their interfaces

Configuration¶

method	does
`get_config()`	running config as JSON or flat CLI
`load_merge_candidate()`	stage a merge — native JSON, gNMI-style, or CLI
`load_replace_candidate()`	stage a full replace
`compare_config()`	diff the staged change against running
`commit_config()`	checkpoint, then apply in one transaction
`commit_config(revert_in=...)`	confirmed commit with auto-revert timer
`confirm_commit()`	accept a pending confirmed commit
`has_pending_commit()`	check for a pending confirmed commit
`discard_config()`	drop the staged change (client-side only)
`rollback()`	restore the pre-commit checkpoint, or reject a pending confirm

The candidate workflow is emulated client-side on top of SR Linux's transactional JSON-RPC set — the configuration management guide explains exactly how.

Tools¶

method	does
`cli()`	run CLI commands, text or structured JSON output
`ping()`	ping from the device, per network-instance
`traceroute()`	traceroute from the device, per network-instance

Not supported¶

SR Linux has no equivalent for these; they raise NotImplementedError:

get_probes_config() / get_probes_results() — no RPM/SLA probe infrastructure
get_firewall_policies() — no zone-based firewall
get_ntp_peers() — SR Linux only supports NTP servers, not symmetric peers
get_route_to(longer=True)

Two get_config() targets always return empty strings rather than raising:

retrieve="candidate" — the candidate exists only client-side
retrieve="startup" — the startup config is not retrievable via JSON-RPC
