PMUX Mode of the IO Aggregator
This chapter describes the various configurations applicable in PMUX mode.
Configuring the Commands Without a Separate User
Account
You can now configure and specify the commands that were available in the PMUX mode of the I/O
Aggregator without having to configure a user profile to access the PMUX mode. As a result, you do not
need to define separate user accounts with permissions to access the PMUX mode on the switch. The
user profile that you defined to access and log in to the switch is sufficient to configure these commands.
This chapter contains sections that describe the configuration settings that were previously available in
the PMUX mode (until Release 9.2(0.0)), which you can now configure without the need for an exclusive,
separate user account.
Link Layer Discovery Protocol (LLDP)
Link layer discovery protocol (LLDP) advertises connectivity and management from the local station to
the adjacent stations on an IEEE 802 LAN.
LLDP facilitates multi-vendor interoperability by using standard management tools to discover and make
available a physical topology for network management. The Dell Networking operating software
implementation of LLDP is based on IEEE standard 801.1ab.
The starting point for using LLDP is invoking LLDP with the protocol lldp command in either
CONFIGURATION or INTERFACE mode.
The information LLDP distributes is stored by its recipients in a standard management information base
(MIB). You can access the information by a network management system through a management
protocol such as simple network management protocol (SNMP).
An Aggregator auto-configures to support the link layer discovery protocol (LLDP) for the auto-discovery
of network devices. You can use CLI commands to display acquired LLDP information, clear LLDP
counters, and debug LACP operation.
Configure LLDP
Configuring LLDP is a two-step process.
1. Enable LLDP globally.
2. Advertise TLVs out of an interface.
