Chapter 7 Configuring the Connection
Configuring the Connection Mode
Options
The following topology-related parameters are included in the connection mode command.
Note that some options are relevant for cascaded topologies only.
•
Connection mode
— Can be any one of the following, depending on the physical installation of the
SCE platform:
–
Inline — single SCE platform inline
–
Receive-only — single SCE platform receive-only
–
Inline-cascade — two cascaded SCE platforms inline
Note
When the 'inline-cascade' connection mode is configured, extra care should be given to the configuration
of the link shapers. Configuring the shaper in an aggressive manner might result in very high rate of
tail-dropped packets. In extreme situations, packets that are used for the High Availability protocol
monitoring and control may be dropped. Thus, an extreme situation could result in false detection of a
failure in the SCE platform and an unnecessary switchover between the active and standby SCE
platforms.
–
Receive-only-cascade — two cascaded SCE platforms receive-only
Default —
inline
•
sce-id
— In cascaded topologies, defines which link is connected to this SCE platform.
The sce-id parameter, which identifies the SCE platform, replaces the physically-connected-link
parameter, which identified the link. This change was required with the introduction of the SCE8000
GBE platform, which supports multiple links. In the SCE8000 10GBE, the number assigned to the
sce-id parameter (0 or 1) will be defined as the of number of the physically-connected-link.
Note
For backwards compatibility, the physically-connected-link parameter is currently still recognized.
Possible values are '0' and '1'.
Not applicable to single SCE platform topologies.
