Command History
Release Modification
11.3NA This command was introduced.
Usage Guidelines This command activates debugging of messages generated in the PHY system, which is the physical
layer where upstream and downstream activity between the Cisco CMTS and the HFC network is
controlled. When this command is activated, any messages generated in the PHY system are displayed
on the Cisco CMTS console.
Examples The following is typical output from the debug cable phy command.
cmts_phy_init: mac_version == BCM3210_FPGA
bcm3033_set_tx_sym_rate(5056941)
stintctl = 0x54484800
bcm3033_set_tx_if_freq(44000000)
stfreqctl = 0x5BAAAAAA
cmts_phy_init_us: U0 part_id = 0x3136, revid = 0x05, rev_id2 = 0x64
cmts_phy_init: mac_version == BCM3210_FPGA
Media access controller chip version.
