Configuring The Connection Mode Example; Monitoring The Connection Mode - Cisco SCE8000 Configuration Manual

Monitoring the Connection Mode

Configuring the shaper in an aggressive manner might result in very high rate of tail-dropped packets.
Note
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.
•
•
Note If the external-bypass option is configured, two optical bypass devices must be properly connected, one
on each link. If an optical bypass device is not detected, the command is executed but a warning is issued.
The system then enters warning mode until either the command is changed, or the presence of an optical
bypass device is detected.
•
•
Do not change the connection mode unless the physical installation has been changed.
Note
From the SCE(config if)# prompt, type connection-mode inline|receive-only on-failure
Step 1
bypass|external-bypass|cutoff and press Enter.

Configuring the Connection Mode Example

This example defines a single-SCE platform, dual link, receive-only topology. The link mode on-failure.
SCE(config if)# connection-mode receive-only

Monitoring the Connection Mode

From the SCE> prompt, type show interface linecard 0 connection-mode and press Enter.
Step 1
Displays the connection mode configuration.

Default — inline
On-failure — This parameter determines the behavior of the system when the SCE platform either
has failed or is booting:
cut the traffic (cutoff)
–
bypass the traffic (bypass)
–
automatically direct traffic through the external bypass module (external-bypass)
–
Default:
inline mode: external-bypass
–
Not applicable to receive-only topologies.
