vlan
Note The switch supports only Ethernet VLANs. You can configure parameters for FDDI and Token Ring
VLANs and view the results in the vlan.dat file, but these parameters are not used.
•
are are-number : defines the maximum number of all-routes explorer (ARE) hops for TrCRF
VLANs. The range is 0 to 13. The default is 7.
•
backupcrf {enable | disable} : specifies the backup CRF mode for TrCRF VLANs.
• bridge { bridge-number| type }: specifies the logical distributed source-routing bridge, the bridge
that interconnects all logical rings having this VLAN as a parent VLAN in FDDI-NET, Token
Ring-NET, and TrBRF VLANs. The range is 0 to 15. The default bridge number is 0.
•
exit : applies changes, increments the VLAN database revision number (VLANs 1 to 1005 only), and
exits VLAN configuration mode.
• media : defines the VLAN media type.
–
ethernet is Ethernet media type (the default).
–
fddi is FDDI media type.
–
fd-net is FDDI network entity title (NET) media type.
– tokenring is Token Ring media type or TrCRF.
–
tr-net is Token Ring network entity title (NET) media type or TrBRF media type.
• mtu mtu-size : specifies the maximum transmission unit (MTU) (packet size in bytes). The range is
1500 to 18190. The default is 1500 bytes.
•
name vlan-name : names the VLAN with an ASCII string from 1 to 32 characters that must be unique
within the administrative domain. The default is VLANxxxx where xxxx represents four numeric
digits (including leading zeros) equal to the VLAN ID number.
•
no : negates a command or returns it to the default setting.
•
parent parent-vlan-id : specifies the parent VLAN of an existing FDDI, Token Ring, or TrCRF
VLAN. The range is 0 to 1005. The default parent VLAN ID is 0 (no parent VLAN).
• ring ring-number : defines the logical ring for an FDDI, Token Ring, or TrCRF VLAN. The range is
1 to 4095.
•
said said-value : specifies the security association identifier (SAID) as documented in IEEE 802.10.
The range is 1 to 4294967294, and the number must be unique within the administrative domain.
The default value is 100000 plus the VLAN ID number.
• shutdown : shuts down VLAN switching on the VLAN. This command takes effect immediately.
Other commands take effect when you exit VLAN configuration mode.
•
state : specifies the VLAN state:
– active means the VLAN is operational (the default).
–
suspend means the VLAN is suspended. Suspended VLANs do not pass packets.
• ste ste-number : defines the maximum number of spanning-tree explorer (STE) hops for TrCRF
VLANs. The range is 0 to 13. The default is 7.
•
stp type : defines the spanning-tree type for FDDI-NET, Token Ring-NET, or TrBRF VLANs.
– ieee for IEEE Ethernet STP running source-route transparent (SRT) bridging.
–
ibm for IBM STP running source-route bridging (SRB).
