Configuring timing references

Use the following CLI syntax to configure timing reference parameters. The source port specified for ref1 and ref2 is dependent on the router model type and chassis slot. See the details in the specific command descriptions in the 7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide.

The following shows a timing reference configuration example for the router:

ALA-12>config>system>sync-if-timing# info
----------------------------------------------
            ref-order ref2 ref1 bits
            ref1
                source-port 3/1/1
                no shutdown
            exit
            ref2
                source-port 6/1/2
                no shutdown
            exit
            bits
                interface-type ds1 esf
                no shutdown
            exit
