VLANs are configured with a name, VLAN ID number (VID), and port members. (For dynamic VLANs, refer to chapter 3, "GVRP" .) By default, the switches covered in this guide are 802.1Q VLAN-enabled.

(The HP 6120G/XG switch allows up to 256 VLANs and the HP 6120XG switch allows up to 1024 (vids up to 4094) VLANs of - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 37

For example, if the switch is configured with the default VLAN plus three protocol-based VLANs that include IPX, - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 41
Bootp: If you are using DHCP/Bootp to acquire the switch's configuration, packet time-to-live, and TimeP information, you must designate the VLAN on which DHCP is configured for this purpose as the Primary VLAN. (In the factory-default configuration, the DEFAULT_VLAN is the Primary VLAN.) ■ Per-VLAN - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 42

using dynamic VLANs, include the port configuration planning necessary to support this feature. (Refer to chapter 3, "GVRP" .) By default, VLAN support is enabled for up to 256 VLANs. 2. Configure at least one VLAN in addition to the default VLAN. 3. Assign the desired switch ports to the new VLAN - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 45
. Thus, connecting a multiple forwarding database switch to a single forwarding database switch where multiple VLANs exist imposes some cabling and port VLAN assignment restrictions. Table 2-4 illustrates the functional difference between the two database types. Table 2-4. Example of Forwarding - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 46
is not a problem for a switch with a multiple forwarding database because the switch allows multiple instances of a given MAC address; one for each valid destination. However, a switch with a single forwarding database allows only one instance of a given MAC address.

This can be any number from 2 to 4094 that is not already being used by another VLAN. (The switch reserves "1" for the default VLAN.)

created VLAN context. If you do not specify an optional name, the switch assigns a name in the default format: VLANn where n is the < vid > assigned to the not deliverable. A "Caution" message appears in the CLI if you configure IPv4 in protocol VLAN that does not already include the arp protocol - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 66
is empty, a Secure Management VLAN is not configured in the switch. Refer to "The Secure Management VLAN" on page 2-48 Figure 2-25. Example of Creating a New, Port-Based, Static VLAN To go to a different VLAN context level, such as to the default VLAN: ProCurve(vlan-100)# vlan default_vlan ProCurve - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 67
and dynamic VLAN operation, refer to chapter 3, "GVRP" .) For example, suppose a dynamic VLAN with a VID of 125 exists on the switch. The following command converts the VLAN to a port-based, static VLAN. ProCurve(config)# static-vlan 125 Configuring Static VLAN Per-Port Settings. The vlan - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 68
specified VLAN to Auto operation. Note that Auto is the default per-port setting for a static VLAN if GVRP is running on the switch. (For information on dynamic VLAN and GVRP operation, refer to chapter 3, "GVRP", in this guide.) For example, suppose you have a VLAN named VLAN100 with a VID of 100 - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 69
will need to use either the CLI or the menu interface (available by Telnet from the web browser interface). 1. Click on the Configuration tab. 2. Click on [Vlan Configuration]. 3.

be an untagged member of that VLAN. This is the case where the port is connected to a non 802.1Q-compliant device or is assigned to only one VLAN. For example, if port 7 on an 802.1Q-compliant switch is assigned to only the Red VLAN, the assignment can remain "untagged" because the - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 71
connected to these ports do not have to be 802.1Q-compliant. • Because both the Red VLAN and the Green VLAN are assigned to port Y5, at least one of the VLANs must be tagged for this port. ■ In both switches: The ports on the link between the two switches must be configured the - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 72
which it is configured. That is, if the Red VLAN has a VID of 10 in switch X, then 10 must also be used for the Red VID in switch Y. VID Numbers Figure 2-27. Example of VLAN in which the VLAN occurs. Also, the ports connecting two 802.1Q devices should have identical VLAN configurations. 2-44 - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 73
■ If all end nodes on a port comply with the 802.1Q standard and are configured to use the correct VID, then, you can configure all VLAN assignments and figure 2-7 • "Tagged Packet Forwarding" and figure 2-8 Example. In the following network, switches X and Y and servers S1, S2, and the AppleTalk - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 74
link, their VLAN configurations must match. Switch X Switch Y Port AT-1 configurations on ports connected by the same link must match. Because ports X2 and Y5 are opposite ends of the same point-to-point connection, both ports must have the same VLAN configuration; that is, both ports configure - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 75
VLAN. You can partition the switch into multiple virtual broadcast domains by configuring one or more additional VLANs and moving ports from the default VLAN to the new VLANs.

Example of Potential Security Breaches In figure 2-30, Workstation 1 has management access to all three switches through the Management VLAN, while the PCs do not. This is because configuring a switch to recognize a Management VLAN automatically excludes - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 78
page 2-50.). Hubs dedicated to connecting management stations to the Management VLAN can also be included in the above topology. Note that any device connected to a hub in the Management VLAN will also have Management VLAN access. 3. Configure the Management VLAN on the selected switch ports. 2-50 - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 79
if you log off your Telnet connection or execute write memory and reboot the switch. Configuration In order to enable management-vlan, oobm must be disabled first, since the two are mutually exclusive. For example, suppose you have already configured a VLAN named My_VLAN Syntax: [no] management - HP 6120XG | HP ProCurve Series 6120 Blade Switches Advanced Traffic Management G - Page 80
