Cabletron Systems 7C04-R, 7C03 manual Destination Port

Using the 7C0x SmartSwitch Bridge View

Destination Port

Displays the port or ports to which frames that have the specified source address and were received on the specified port or ports will be forwarded. Note that packets with the specified source address received on the specified port or ports will be blocked from any ports not listed in this field.

If the number of Destination Ports exceeds what the Destination Ports column is able to display, Destination Ports for that filter appear as a hex string that maps to actual port numbers.

For example, a Destination Port entry of B54180E0 represents ports 1, 3, 4, 6, 8, 10, 16, 17, 25, 26, and 27. Here’s how to translate the hex string to port numbers:

1. Translate each hex integer into a four-digit binary value:

B	5	4	1	8	0	E	0
1011	0101	0100	0001	1000	0000	1110	0000

2. Each “1” in the binary bitmask represents a Destination Port number:

B	5	4	1	8	0	E	0
1011	0101	0100	0001	1000	0000	1110	0000
1,X,3,4	X,6,X,8	X,10,X,X	X,X,X,16	17,X,X,X	X,X,X,X	25,26,27,X	X,X,X,X

Status

Indicates the assigned permanence of the entry:

•permanent—The entry won’t be aged out or deleted on reset.

•deleteOnReset—The entry will be deleted when the bridge is reset.

•deleteOnTimeout—The entry is subject to the ageing timer.

The buttons at the bottom of the window provide the following functions:

The Delete button is only available when the Filtering Database window is showing Static entries and one entry in the list is selected. Use the Delete button to remove an entry from the Static Table; see Deleting a Static Table Entry,

page 6-19.

The Change button is only available when the Filtering Database window is showing Static entries and one entry in the list is selected. Use the Change button to change the selected port’s receive port/destination ports settings; see Changing Forwarding and Static Database Entries, page 6-18.

The Add to Static Table button is only available when the Filtering Database window is showing Forwarding entries and one entry in the list is selected. Use it to add a forwarding entry to the static database. Since the Forwarding table cannot be edited, you must add an entry to the Static Table in order to change or delete it, as desired.
