=head1 Neighbor Relations on Juniper EX
The LLDP configuration should look like:
lldp {
management-address 10.0.0.1;
port-id-subtype interface-name;
interface all;
}
=head1 VRFs and NXOS
Netdsico at this time does not support VRFs. In particular, overlapping IP
address spaces will not be shown in the interface.
However if you're running Cisco NXOS and do not have overlapping IP address
space, then you can use the NXOS SSHCollector profile for that platform.

=head1 SNMPv3 Support on Cisco IOS
To access per-VLAN MAC address tables we use SNMPv3 contexts. In Cisco IOS
the access control is per-context so for each context (VLAN) you need to permit
access from the poller.
You should already have something like the following to enable SNMPv3 from Netdisco at 192.0.2.1:
snmp-server view myv3view iso included
snmp-server group myv3group v3 priv read myv3view
snmp-server user myv3user myv3group v3 auth md5 PASSWORD priv des PASSWORD
snmp-server host 192.0.2.1 version 3 auth myv3user
Then set the authorization:
snmp-server group myv3group v3 auth
snmp-server group myv3group v3 auth context vlan- match prefix
If the second command above is rejected, you have an older version of IOS and must
enter a statement for each active VLAN on the device:
snmp-server group myv3group v3 priv context vlan-1
snmp-server group myv3group v3 priv context vlan-2
snmp-server group myv3group v3 priv context vlan-3
... etc
=head1 Linux SNMP Service (Agent)
Install the C<snmpd> (SNMP agent) and C<lldpd> (neighbor discovery) packages.
Edit the C</etc/snmp/snmpd.conf> file:
# AGENT BEHAVIOUR
# comment out: agentAddress udp:127.0.0.1:161
agentAddress udp:161,udp6:[::1]:161
# ACCESS CONTROL
rocommunity <your-secret> <management-device-IP/net>
# SYSTEM INFORMATION
sysServices 76
# (default is 72, 74 is layer2 bridge/switch, 76 for layer3 router/gateway)
If running a firewall, allow SNMP traffic in on UDP port 161.
Edit the C</etc/default/lldpd> file:
DAEMON_ARGS="-k -x -l -m <Mgmt-IP>"
# <Mgmt-IP> is the IP to advertise for Netdisco to connect
Restart C<snmpd> and C<lldpd> services when you have configured them.
This assumes you're using LLDP on your network. If you use CDP then the
C<lldpd> daemon can support that protocol - see the manual page for details.
