ZXR10 2900E Series Configuration Guide
1. Managed devices, which can communicate over the Internet. Each device contains
an agent.
2. NMS, The network management process shall be able to communicate over the
Internet.
3. The protocol used for the exchange of management information between the switching
agent process and the NMS, that is, SNMP.
An NMS collects data by polling the agents that reside in the managed devices. The agents
in the managed devices can report errors to NMSs at any time before the NMSs poll them.
These errors are called traps. When a trap occurs to a device, the NMS can be used to
query the device (suppose it is reachable) and obtain more information. Snmp v2c and
v3 also support inform (a SNMPv2 Trap that need response) to inform abnormal events to
NMS. If receives inform message NMS will send a acknowledgement packet to switch. If
switch hasn't received acknowledgement packet from NMS in a period time it will resend
the original inform message twice.
All variables in the network are stored in the MIB. SNMP monitors network device status
by querying the related object values in the agent MIB. ZXR10 2900E implements the
standard MIB and private MIB defined in rfc2233, rfc1493, rfc2665 and rfc2819.
Configuring SNMP
The SNMP configuration includes the following commands:
Command
zte(cfg-snmp)#set engineID
zte(cfg-snmp)#set recvpacket <0-100>
zte(cfg-snmp)#create community <string>{public |
private}[ingress-acl-basic-number <1-99>]
zte(cfg-snmp)#create view < string >[{include | exclude}<mib-oid>]
zte(cfg-snmp)#set community <string> view <string>
