Chapter 2 Catalyst 2350 Cisco IOS Commands
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. This parameter identifies the TrBRF to which a TrCRF belongs and is required when
defining a TrCRF. The range is 0 to 1005. The default parent VLAN ID is 0 (no parent VLAN) for
FDDI and Token Ring VLANs. For both Token Ring and TrCRF VLANs, the parent VLAN ID must
already exist in the database and be associated with a Token Ring-NET or TrBRF VLAN.
remote-span: configure the VLAN as a Remote SPAN (RSPAN) VLAN. When the RSPAN feature
•
is added to an existing VLAN, the VLAN is first deleted and is then recreated with the RSPAN
feature. Any access ports are deactivated until the RSPAN feature is removed. If VTP is enabled, the
new RSPAN VLAN is propagated by VTP for VLAN-IDs that are lower than 1024. Learning is
disabled on the VLAN. See the
ring ring-number: defines the logical ring for an FDDI, Token Ring, or TrCRF VLAN. The range is
•
1 to 4095. The default for Token Ring VLANs is 0. For FDDI VLANs, there is no default.
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 config-vlan mode.
•
state: specifies the VLAN state:
–
–
ste ste-number: defines the maximum number of spanning-tree explorer (STE) hops. This keyword
•
applies only to 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. For
•
FDDI-NET VLANs, the default STP type is ieee. For Token Ring-NET VLANs, the default STP
type is ibm. For FDDI and Token Ring VLANs, the default is no type specified.
–
–
–
•
tb-vlan1 tb-vlan1-id and tb-vlan2 tb-vlan2-id: specifies 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. If no value is specified, 0 (no transitional bridging) is assumed.

active means the VLAN is operational (the default).
suspend means the VLAN is suspended. Suspended VLANs do not pass packets.
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).
