Configuring LLDP
The Link Layer Discovery Protocol (LLDP) allows network managers to troubleshoot and enhance network
management by discovering and maintaining network topologies over multi-vendor environments. LLDP
discovers network neighbors by standardizing methods for network devices to advertise themselves to other
system, and to store discovered information. Device discovery information includes:
• Device Identification
• Device Capabilities
• Device Configuration
The advertising device transmits multiple advertisement message sets in a single LAN packet. The multiple
advertisement sets are sent in the packet
Type Length Value (TLV) field. LLDP devices must support chassis and
port ID advertisement, as well as system name, system ID, system description, and system capability
advertisements.
The
LLDP Properties page contains fields for configuring LLDP.
To open the
LLDP Properties Page, click Security → LLDP → LLDP Properties in the tree view .
Figure 1-1. LLDP Properties
Enable LLDP — Indicates if LLDP is enabled on the device. The possible field values are:
Checked — Indicates that LLDP is enabled on the device.
Unchecked — Indicates that LLDP is disabled on the device. This is the default value.

5
Updates Interval (5-32768) — Indicates that rate at which LLDP advertisement updates are sent. The
possible field range is 5 - 32768 seconds. The default value is 30 seconds.
Hold Time (2-10) — Indicates the amount of time that LLDP packets are held before the packets are dis-
carded. The possible field range is 2 - 10 seconds. The field default is 4 seconds.
Reinitializing Delay (1-10) — Indicates the amount of time that passes between disabling LLDP and when
reinitializing begins. The possible field range is 1 - 10 seconds. The field default is 2 seconds.
Transmit Delay (1-8192) — Indicates the amount of time that passes between successive LLDP frame trans-
missions due to changes in the LLDP local systems MIB. The possible field value is
1 – 8192 seconds. The field default is 2 seconds.
Configuring LLDP Using CLI Commands
The following is an example of the CLI commands:
Table 1-1. LLDP Properties CLI Commands
CLI Command Description

Defining SNMP Parameters
Simple Network Management Protocol (SNMP) provides a method for managing network devices. Devices
supporting SNMP run a local software (agent).
The SNMP agents maintain a list of variables, which are used to manage the device. The variables are defined in
the Management Information Base (MIB). The MIB contains the variables controlled by the agent. The SNMP
protocol defines the MIB specification format, as well as the format used to access the information over the
network.
Access rights to the SNMP agents are controlled by access strings. To communicate with the device, the
Embedded Web Server submits a valid community string for authentication. To open the SNMP page, click
System → SNMP in the tree view.
This section contains information for managing the SNMP configuration.
Defining SNMP Global Parameters
The SNMP Global Parameters page permits enabling both SNMP and Authentication notifications. To open
the
SNMP Global Parameters page, click System → SNMP → Global Parameters in the tree view.
Figure 1-8. Global Parameters

15
Local Engine ID (10 - 64 Hex Characters) — Indicates the local device engine ID. The field value is a
hexadecimal string. Each byte in hexadecimal character strings is two hexadecimal digits. Each byte can be
separated by a period or a colon. The Engine ID must be defined before SNMPv3 is enabled.
For stand-alone devices select a default Engine ID that is comprised of Enterprise number and the default MAC
address.
Use Default — Uses the device generated Engine ID. The default Engine ID is based on the device MAC
address and is defined per standard as:
First 4 octets — first bit = 1, the rest is IANA Enterprise number.
Fifth octet — Set to 3 to indicate the MAC address that follows.
Last 6 octets — MAC address of the device.
SNMP
Notifications — Enables or disables the router sending SNMP notifications.
Authentication Notifications — Enables or disables the router sending SNMP traps when authentication fails.
Enabling SNMP Notifications
1 Open the SNMP Global Parameters page.
2 Select Enable in the SNMP Notifications field.
3 Click Apply Changes .
SNMP notifications are enabled, and the device is updated.
Enabling Authentication Notifications
1 Open the SNMP Global Parameters page.
2 Select Enable in the Authentication Notifications field.
3 Click Apply Changes .

Indicates the local device engine ID. The field
values is a hexadecimal string. Each byte in
hexadecimal character strings is two hexadecimal
digits. Each byte can be separated by a period or
colon. The Engine ID must be defined before
SNMPv3 is enabled.

Defining SNMP View Settings
SNMP Views provides access or blocks access to device features or feature aspects. For example, a view can be
defined which states that SNMP group A has read only (R/O) access to Multicast groups, while SNMP group B
has read-write (R/W) access to Multicast groups. Feature access is granted via the MIB name, or MIB Object ID.
The Up and Down arrows allow navigating through the MIB tree, and MIB branches.
