SNMP and CLI discovery support

MPLS Manager uses both Simple Network Management Protocol (SNMP) and command line interface (CLI) to perform discovery on the supported devices in the managed MPLS network. MPLS Manager supports IPv4 SNMP; SNMPv1, v2c, and v3; and Telnet and Secure Shell (SSH) CLI.

Discovery sources for supported devices shows the discovery sources for the supported devices.

1  SNMP-discovered objects are monitored for status, but CLI-discovered objects are not.
Cisco IOS	MPLS-TE-MIB, MPLS-LSR-MIB, MPLS-LDP-MIB, and CLI MPLS Manager uses: SNMP discovery to discover TE tunnel and TE LSP objects on Cisco IOS devices. CLI discovery to discover nested link/node protected TE tunnel objects on Cisco IOS devices. SNMP discovery to discover LDP LSP objects on Cisco IOS devices. If SNMP discovery fails or is not supported by the Cisco IOS device, MPLS Manager uses CLI discovery to discover the LDP LSP objects. SNMP discovery to discover non-targeted LDP adjacency objects on Cisco IOS devices. CLI discovery to discover RSVP session objects on Cisco IOS devices.	CISCO-IETF-PW-MIB,CISCO-IETF-PW-MPLS-MIB,MPLS-LDP-MIB, and CLI MPLS Manager uses: SNMP discovery to discover LDP VPWS objects on Cisco IOS devices. CLI discovery to discover LDP VPLS objects on Cisco IOS devices. CLI discovery to discover VLAN objects that are associated with the Cisco IOS VPWS and VPLS objects. SNMP discovery to discover targeted LDP adjacency objects that are associated with the Cisco IOS VPWS and VPLS objects.	MPLS-VPN-MIB MPLS Manager uses SNMP discovery to discover L3VPN objects on Cisco IOS devices. If SNMP discovery fails or is not supported by the Cisco IOS device, MPLS Manager uses CLI discovery to discover the L3VPN objects.

CLI discovery to discover VLAN objects that are associated with the Cisco IOX VPWS and VPLS objects. SNMP discovery to discover targeted LDP adjacency objects that are associated with the Cisco IOX VPWS and VPLS objects.	MPLS-L3VPN-STD-MIB MPLS Manager uses SNMP discovery to discover L3VPN objects on Cisco IOX devices.
Huawei	CLI MPLS Manager uses CLI discovery to discover LDP LSP objects on Huawei devices.	MPLS-LDP-STD-MIB and CLI MPLS Manager uses: CLI discovery to discover VPWS objects on Huawei devices. CLI discovery to discover VLAN objects that are associated with the Huawei VPWS objects. SNMP discovery to discover targeted LDP adjacency objects that are associated with the Huawei VPWS objects.	MPLS-VPN-MIB MPLS Manager uses SNMP discovery to discover L3VPN objects on Huawei devices. If SNMP discovery fails or is not supported by the Huawei device, MPLS Manager uses CLI discovery to discover the L3VPN objects.
Juniper M/T	JUNIPER-MPLS-MIB, JUNIPER-MPLS-LDP-MIB, JUNIPER-RSVP-MIB, and CLI MPLS Manager uses: SNMP and CLI discovery to discover TE tunnel and TE LSP objects on Juniper M/T devices. SNMP discovery to discover P2MP LSP and subLSP objects on Juniper M/T devices. CLI discovery to discover LDP LSP objects on Juniper M/T devices. SNMP discovery to discover non-targeted LDP adjacency objects on Juniper M/T devices. If SNMP discovery fails or is not supported by the Juniper M/T device, MPLS Manager uses CLI discovery to discover the non-targeted LDP adjacency objects. SNMP discovery to discover RSVP session objects on Juniper M/T devices.	JUNIPER-VPN-MIB, JUNIPER-MPLS-LDP-MIB, and CLI MPLS Manager uses: SNMP discovery to discover BGP VPWS and VPLS objects on Juniper M/T devices. CLI discovery to discover LDP VPLS objects on Juniper M/T devices. CLI discovery to discover VLAN objects that are associated with the Juniper M/T VPLS objects. SNMP discovery to discover targeted LDP adjacency objects that are associated with the Juniper M/T LDP VPLS objects. If SNMP discovery fails or is not supported by the Juniper M/T device, MPLS Manager uses CLI discovery to discover the targeted LDP adjacency objects.	JUNIPER-VPN-MIB and CLI MPLS Manager uses SNMP discovery to discover L3VPN objects on Juniper M/T devices. If SNMP discovery fails or is not supported by the Juniper M/T device, MPLS Manager uses CLI discovery to discover the L3VPN objects. MPLS Manager also uses CLI discovery to discover multicast groups and their relationship to P2MP LSPs.
