	Port Context
	For the purpose of management, the 16 Fast Ethernet ports of the 7600
	Card are divided into four contexts. These are displayed in the following
	table:
	.
	Table 3-3Port Context
	Contex	#0	Contex	#1	Contex	#2	Contex	#3
	t		t		t		t
	9	10	11	12	13	14	15	16
	1	2	3	4	5	6	7	8

The management menus and commands focus on one context at a time. Each menu displays the currently active context. To work with a certain port, first use the table to ascertain to which context the port belongs. For example, ports 1, 2, 9, 10 belong to Context #1. Then change to that context by entering “.n” where n is the context number. From that point on, the menus related to the ports in that context are displayed.

The Multi-context Fast Setup procedure described in the next section runs though all contexts automatically so that you can set up all the ports in the device in one continuous dialog.

Setup Procedure The following describes the main steps of the Multi-context Fast Setup:

Sections

QVirtual Network Configuration. Each Fast Ethernet port is assigned to a logical bridge. Initially, all ports default to the “admin” vLAN. Bridge 0 is the default bridge to which port 1 is always initially assigned for ease of management setup.

QEmulated LAN (ELAN) Configuration. The ELAN name and LES address can be assigned for each logical bridge specified in the virtual network configuration with an ATM connection. This information is necessary for communication within virtual networks. All logical bridges assigned to the same LES address or ELAN name, are defined as being in the same ELAN.

QManagement Configuration. The IP address and Network Management Station (NMS) address, with their default gateways and
