Switch Configuration SmartStack STS16-20RM/STS16-20FRM Token Ring Switches, P/N: 9032957-01
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 or the stack is equipped with a SSIM-
H2-02 Fast Ethernet - Translational Switch SmartStack Interface Module. It can be
set to
Primary (default) Secondary1 , and Secondary2 .
For each CRF of translational links connected to the same logical Ethernet segment,
a connection attribute must be assigned:
•
Primary
connection—for a main connection to the logical Ethernet segment
(default value for each CRF). This connection is always forwarding if active.
•
Secondary1 —for a backup connection to the logical Ethernet segment. This
connection is always blocking if the primary is active.
•
Secondary2 —for a second backup connection to the logical Ethernet segment.
This connection is always blocking if Primary or Secondary1 are active.
Each CRF of the translational links connected to the same logical Ethernet segment
must have a different connection attribute.
