SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide Switch Configuration
VLAN ID
Numeric ID of the CRF. Possible values are 2 through 1005. Values 1002 through
1005 and 1 are reserved for the default CRFs and BRFs.
VLAN Name
ASCII name associated with the CRF. Up to 32 characters are allowed. The name
must be unique. Neither a BRF nor a CRF must exist with identical names.
Parent VLAN
BRF to which the CRF belongs.
State
Current state of the CRF. Possible values are
Operational
and
Suspended
. CRFs in
operational state are functional. CRFs in suspended state do not pass packets. The
default is operational.
Ring Number
Logical ring number assigned to this CRF. Possible hexadecimal values are
auto
and
0x001
through
0xFFF
. The default is
auto
, meaning that the ring number will
be learned. If the ring number has been learned, the learned ring number will be
prefixed with
A
-.
➽ Note:
A ring number is learned from Source Route Explorer frames (ARE and
STE) and from the MAC protocol. Forwarding of frames between CRFs in SRB
mode is only possible, if the CRFs know their ring numbers. If you are running the
switch in an environment without other bridges/switches, learning of ring numbers
is not possible. Hence manual configuration of ring numbers is required.
Bridging Mode
Bridging mode for this CRF. Possible values are SRB and SRT. The default is SRB.
Max ARE Bridge Hop Count
Maximum number of hops for all-routes explorer (ARE) frames. Possible values
are 1 through 13. The default is 7.
Max STE Bridge Hop Count
Maximum number of hops for spanning tree explorer (STE) frames. Possible
values are 1 through 13. The default is 7.
TS Connection
This parameter is only relevant if the switch is part of a stack equipped with a
SSIM-H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module. It
can be set to
Primary
(default)
Secondary1
, and
Secondary2
.
