Management Address
A management address is normally an IPv4 or IPv6 address that can be used to manage the device.
Management address advertising has two modes: default, or explicitly configured. The default mode is
used when no addresses are configured to be advertised for a given port. If any addresses are
configured to be advertised for a given port, then only those addresses are advertised. This applies
across address types, so for example, if just one IPv4 address is explicitly configured to be advertised
for a port, then no IPv6 addresses will be advertised for that port (since none were configured to be
advertised), even if IPv6 addresses are configured within the system.
If no management address is explicitly configured to be advertised, the Brocade device will use the first
available IPv4 address and the first available IPv6 address (so it may advertise IPv4, IPv6 or both). A
Layer 3 switch will select the first available address of each type from those configured on the following
types of interfaces, in the following order of preference:
• Physical port on which LLDP will be transmitting the packet
• Virtual router interface (VE) on a VLAN that the port is a member of
• Dedicated management port
• Loop back interface
• Virtual router interface (VE) on any other VLAN
• Other physical port
• Other interface
For IPv6 addresses, link-local and anycast addresses will be excluded from these searches.
If no IP address is configured on any of the above, the port's current MAC address will be advertised.
To advertise a IPv4 management address, enter a command such as the following:
device(config)#lldp advertise management-address ipv4 10.157.2.1 ports e 1/4
The management address will appear similar to the following on the remote device, and in the CLI
display output on the Brocade device (
show lldp local-info
):
Management address (IPv4): 10.157.2.1
Syntax:[no] lldp advertise

To support an IPv6 management address, there is a similar command that has equivalent behavior as
the IPv4 command.
To advertise an IPv6 management address, enter a command such as the following:
device(config)#lldp advertise management-address ipv6 2001:DB8::90 ports e 2/7
Syntax:[no] lldp advertise
management-address

ipv4 address
or
ipv6 address
or both are the addresses that may be used to reach higher layer entities
to assist discovery by network management. In addition to management addresses, the advertisement
will include the system interface number associated with the management address.
For
port list
, specify the port(s) in the format [ slotnum /] portnum , where slotnum is required on
chassis devices only. You can list all of the ports individually; use the keyword to specify a range of
ports, or a combination of both. To apply the configuration to all ports on the device, use the keyword
all
instead of listing the ports individually.
Port description
The port description TLV identifies the port from which the LLDP agent transmitted the advertisement.
The port description is taken from the ifDescr MIB object from MIB-II.
