Chapter 4 Configuring ESCON Signal Aggregation
Configuring ESCON Multiplexing Line Card Interfaces
To configure the ESCON multiplexing line cards interfaces, perform the following tasks, starting in
global configuration mode:
Note When forward laser control is enable on an esconphy interface and a loss of light is detected on the port,
the transmitter laser on the corresponding port on the remote node is turned off, regardless of the forward
laser control configuration on the remote esconphy interface.
Example
The following example shows how to configure ESCON multiplexing line card interfaces:
Switch(config)# interface esconphy 10/0/0
Switch(config-if)# cdl flow identifier 100
Switch(config-if)# no shutdown
Switch(config-if)# exit
Displaying the ESCON Multiplexing Line Card Interface Configuration
To display the configuration of ESCON multiplexing line card interfaces, use the following EXEC
command:
Command Purpose
Step 1
Switch(config)# interface esconphy slot/0/port
Switch(config-if)#
Specifies an interface to configure and enters
interface configuration mode.
Step 2
Switch(config-if)# cdl flow identifier number Configures the in-band message channel flow
identifier. The range is 0 to 254.
Note You must configure the other esconphy
interface in the network that supports this
signal with the same flow identifier.
Caution Use unique flow identifiers for each
esconphy interface on the system.
Duplicate flow identifiers might interfere
with APS switchovers.
Step 3
Switch(config-if)# laser control forward
enable
Enables forward laser control on the interface. The
default for esconphy interfaces is enabled.
Step 4
Switch(config-if)# no shutdown Enables the interface.
Step 5
Switch(config-if)# exit
Switch(config)#
Returns to global configuration mode.
Repeat Step 1 through Step 5 for the other esconphy
interfaces on the ESCON multiplexing line card.
Command Purpose
show interfaces {esconphy | portgroup}
slot/subcard/port
Displays the interface configuration.
