Virtual Broadcast Domain

Virtual broadcasts domain is a concept that tends to confine broadcasts in a physical domain, it allows to diminish the bandwidth used by broadcasts, giving more room to the unicast traffic, it also prevent the phenomenon called broadcasts storms to affect the entire network. VBC are not made for a security purposes but to improve the efficiency of the communications in a network. VBC disconnect entities belonging to different domain by avoiding the service traffic (broadcasts) to go through. For instance, an ARP broadcast request sent by a machine which belongs to VBC 1 to a machine belonging to VBC 2 will not have an answer, thus the initiating entity cannot resolve the layer 3 address to a MAC address and consequently cannot communicate with the VBC 2 machine.

Viewing the VBC Mode

get-vlan-mode

get-vlan-mode {runnvram}

Example

SYS_console>get-vlan-mode run

Runtime VLAN mode is disabled

SYS_console>

Setting the VBC mode

set-vlan-mode

There are three modes available: vbc, tag, or one mode can be defined for running session).

none. The modes are mutually exclusive (i.e. only The default value mode is none.

set-vlan-mode <database><VLAN state>

[arg #0] database type - either {runnvramall} [arg #1] VLAN state: either {vbctagnone}

Example

SYS_telnet>set-vlan-mode run vbc

Set run VLAN mode vbc- OK

Creating VBC Domains

set-vbc-domain

The set-vbc-domaincommand is applicable only after enabling the “vbc mode,” using the set-vlan-modecommand. It establishes a Virtual broadcast domain. The port_list value is a dash-separated list of ports to group into a broadcast domain.

set-vbc-domain {runnvramall} <port_list>

For example, to create a virtual broadcast domain of ports 2, 5, and 6, use the following command:

sys_console>set-vbc-domain all 2-5-6
