Port Trunking

Port Status and Configuration

Switch 1:

Ports c1 - c4 configured as a port trunk group.

The multiple physical links in a trunk behave as one logical link

port c1		port a1	Switch 2:
port c2		port a2	Ports a2 and
port c3		port a3
			a4 - a6 are
port c4		port a4
			configured as
port c5		port a5
			a port trunk
port c6		port a6
			group
port c7		port a7
. . .	. . .
port n		port n

	Port Connections and Configuration
	All port trunk links must be point-to-point connections between the switch
	and a router, server, workstation, or another switch configured for port
	trunking. No intervening, non-trunking devices are allowed. It is important to
	note that ports on both ends of a port trunk group must have the same mode
	(speed and duplex) and flow control settings.
	Link Connections
N o t e
	The switch does not support trunking through an intermediate, non-trunking
	device such as a hub, or using more than one media type in a port trunk group.
	Similarly, all links in the same trunk group must have the same speed, duplex,
	and flow control.
	Trunk Group Boundary Requirement with IP Routing Enabled
	on the Series 2800 Switch
	On the Switch 2824 and Switch 2848, trunk groups can generally be specified
	as any grouping of ports on the switch. However, if IP routing is enabled on
	the switch, all of the ports in a given trunk group must be in the same group
	of ports, as shown in table 2.
