vlan (VLAN configuration)
Table 2-34 shows the valid syntax options for different media types.
media {ethernet | fddi | fd-net
| tokenring | tr-net}
(Optional) Specify the VLAN media type. Table 2-34 lists the valid
syntax for each 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 if the VTP v2 mode is
disabled, or TrCRF if the VTP v2 mode is enabled.
• tr-net is Token Ring network entity title (NET) media type if the
VTP v2 mode is disabled or TrBRF media type if the VTP v2
mode is enabled.
mtu mtu-size (Optional) Specify the maximum transmission unit (MTU) (packet
size in bytes). The range is 1500 to 18190.
name vlan-name (Optional) Specify the VLAN name, an ASCII string from 1 to 32
characters that must be unique within the administrative domain.
parent parent-vlan-id (Optional) Specify the parent VLAN of an existing FDDI, Token
Ring, or TrCRF VLAN. This parameter identifies the TrBRF to which
a TrCRF belongs and is required when defining a TrCRF. The range
is 0 to 1005.
ring ring-number (Optional) Specify the logical ring for an FDDI, Token Ring, or
TrCRF VLAN. The range is 1 to 4095.
said said-value (Optional) Enter the security association identifier (SAID) as
documented in IEEE 802.10. The range is 1 to 4294967294 and must
be unique within the administrative domain.
state {suspend | active} (Optional) Specify the VLAN state:
• If active, the VLAN is operational.
• If suspend, the VLAN is suspended. Suspended VLANs do not
pass packets.
ste ste-number (Optional) Specify the maximum number of spanning-tree explorer
(STE) hops. This keyword applies only to TrCRF VLANs. The range
is 0 to 13.
stp type {ieee | ibm | auto} (Optional) Specify the spanning-tree type for FDDI-NET, Token
Ring-NET, or TrBRF VLAN.
• ieee for IEEE Ethernet STP running source-route transparent
(SRT) bridging.
• ibm for IBM STP running source-route bridging (SRB).
• auto for STP running a combination of source-route transparent
bridging (IEEE) and source-route bridging (IBM).
tb-vlan1 tb-vlan1-id
and tb-vlan2 tb-vlan2-id
(Optional) Specify the first and second VLAN to which this VLAN is
translationally bridged. Translational VLANs translate FDDI or
Token Ring to Ethernet, for example. The range is 0 to 1005. Zero is
assumed if no value is specified.
