MIB Viewer

Search, upload, browse, or download from a database of over 11,000 SNMP MIBs. MIB Viewer lets you look up any MIB object by name, OID, or number, view its syntax, access level, and description, trace its place in the MIB tree, and generate ready-to-run SNMP commands — all in your browser.

What's a MIB?

A MIB (Management Information Base) is a structured document that defines the data a device exposes over SNMP — things like interface counters, system uptime, or CPU load. Each module declares a set of named objects, organized into a tree.

What's SNMP?

SNMP (Simple Network Management Protocol) is how network devices — routers, switches, servers — report status and statistics to monitoring tools. It's the protocol; MIBs are the vocabulary it uses to describe what's being asked for.

What's an OID?

An OID (Object Identifier) is the numeric address of one piece of data in a MIB — a dotted sequence like 1.3.6.1.2.1.1.1, read from the root of a global tree down to one specific object. Names are easier to read; OIDs are what's actually sent over the wire.

f2000EAS Series card IP Configuration: This setting controls the DNS name resolution done by the switch. The following modes are supported: 0:No DNS server No DNS server will be used. 1:Configured IPv4 or IPv6 Explicitly provide the valid IPv4 unicast address of the DNS Server in dotted decimal notation. Make sure the configured DNS server could be reachable (e.g. via PING) for activating DNS service. Explicitly provide the valid IPv6 unicast (except linklocal) address of the DNS Server. Make sure the configured DNS server could be reachable (e.g. via PING6) for activating DNS service. 2:From any DHCPv4 interfaces The first DNS server offered from a DHCP lease to a DHCP-enabled interface will be used. 3:From this DHCPv4 interfaces The first DNS server offered from a DHCP lease to a DHCP-enabled interface will be used. 4:From any DHCPv6 interfaces Specify from which DHCPv6-enabled interface a provided DNS server should be preferred. 5:From this DHCPv6 interface The first DNS server offered from a DHCPv6 lease to a DHCPv6-enabled interface will be used
