• VLAN 4, zhp3: for last set of six ports, zre18-zre23
Each VLAN interface is labeled
z h p N
in the file, where
N
is a value from 0-3. Each interface is
untagged and assigned its own IP address (see Figure 7.4).
Figure 7.4: Multiple VLAN Configuration
The S50multivlan script executes the following commands:
• Runs zconfig to create and start four VLANs. Switch ports 0-9 are placed in the first
VLAN, ports 10-19 in the second VLAN, ports 20-21 are placed in the third VLAN, and
ports 22-23 are placed in the fourth VLAN.
/usr/sbin/zconfig zhp0: vlan1=zre0..5
/usr/sbin/zconfig zre0..5=untag1
/usr/sbin/zconfig zhp1: vlan2=zre6..11
/usr/sbin/zconfig zre6..11=untag2
/usr/sbin/zconfig zhp2: vlan3=zre12..17
/usr/sbin/zconfig zre12..17=untag3
/usr/sbin/zconfig zhp3: vlan4=zre18..23
/usr/sbin/zconfig zre18..23=untag4
NOTE: Double periods (..) after vlan1 and untag1 are used to indicate a range of values.
• Runs the Linux ifconfig command for each interface to assign default IP addresses
