Creating Trunk Groups; Usage Guidelines - AMX NXA-ENET8-2POE Operation/Reference Manual

This guide assumes that RADIUS and TACACS+ servers have already been
configured to support AAA. The configuration of RADIUS and TACACS+ server
software is beyond the scope of this guide. Refer to the documentation provided with
the RADIUS and TACACS+ server software.
1.
Click Configuration, Security, AAA.
2.
Configure the authentication method for management client types, the common server timing parameters,
and address, UDP port, and secret key for each required RADIUS or TACACS+ server.
3.
Click Save.

Creating Trunk Groups

You can create multiple links between devices that work as one virtual, aggregate link. A port trunk offers a
dramatic increase in bandwidth for network segments where bottlenecks exist, as well as providing a fault-
tolerant link between two switches.
The switch supports both static trunking and dynamic Link Aggregation Control Protocol (LACP). Static
trunks have to be manually configured at both ends of the link, and the switches must comply with the Cisco
EtherChannel standard. On the other hand, LACP configured ports can automatically negotiate a trunked link
with LACP-configured ports on another device. You can configure any number of ports on the switch to use
LACP, as long as they are not already configured as part of a static trunk. If ports on another device are also
configured to use LACP, the switch and the other device will negotiate a trunk between them. If an LACP
trunk consists of more than eight ports, all other ports will be placed in standby mode.
Should one link in the trunk fail, one of the standby ports will automatically be activated to replace it.

Usage Guidelines

Besides balancing the load across each port in the trunk, the other ports provide redundancy by taking over the
load if a port in the trunk fails.
However, before making any physical connections between devices, configure the trunk on the devices at both
ends. When using a port trunk, take note of the following points:

Finish configuring port trunks before you connect the corresponding network cables between
switches to avoid creating a loop.
You can create up to 14 trunks on a switch, with up to 16 ports per trunk.
The ports at both ends of a connection must be configured as trunk ports.
When configuring static trunks on switches of different types, they must be compatible with the
Cisco EtherChannel standard.
The ports at both ends of a trunk must be configured in an identical manner, including
communication mode (i.e., speed, duplex mode and flow control), VLAN assignments, and CoS
settings.
Any of the Gigabit ports on the front panel can be trunked together, including ports of different
media types.
All the ports in a trunk have to be treated as a whole when moved from/to, added or deleted from a
VLAN.
STP, VLAN, and IGMP settings can only be made for the entire trunk.
