Command Reference show controllers cable-modem filters To display the registers in the MAC hardware that are used for filtering received frames, use the show controllers cable-modem filters command in privileged EXEC mode. show controllers cable-modem number filters Syntax Description number Controller number inside the cable modem. Command Mode Privileged EXEC Usage Guidelines This command first appeared in Cisco IOS Release 11.3 NA. Some of the filtering parameters are MAC hardware addresses, Service IDs (SIDs), and upstream channel IDs. Examples MAC and SID filter information is displayed in the following example: uBR904# show controllers cable-modem 0 filters downstream mac message processing: ds_mac_da_filters: filter_1=0010.7b43.aa01, filter_2=0000.0000.0000 filter_3=0000.0000.0000, filter_4=0000.0000.0000 ds_mac_da_filter_ctrl=0x71, ds_mac_msg_sof=0x0000 ds_mac_da_mc=01E02F00 map_parser_sids: sid_1=0x0000, sid_2=0x0000, sid_3=0x0000, sid_4=0x0000 ds_mac_filter_ctrl=0x00, us_channel_id=0x0000 ds_pid=0x0000, mac_msg_proto_ver=FF 00 reg_rang_req_sid=0x0000 downstream data processing: ds_data_da_filter_table: filter_1 0010.7b43.aa01, filter_2 0000.0000.0000 filter_3 0000.0000.0000, filter_4 0000.0000.0000 ds_data_da_filter_ctrl=0x61, ds_pdu_sof=0xDEAD ds_data_da_mc=01000000 upstream processing: us_ctrl_status=0x04, Minislots per request=0x01 burst_maps: map[0]=0 map[1]=0 map[2]=0 map[3]=0 bytes_per_minislot_exp=0x04 us_map_parser_minislot_adv=0x03, ticks_per_minislot=0x08, maint_xmit=0x0001 us_sid_table: sid_1=0x0000, sid_2=0x0000, sid_3=0x0000, sid_4=0x0000 max_re_req=0x0010, rang_fifo=0x00 Table 5 briefly describes some of the fields shown in the display.
