The following example shows typical output for IPC debugging messages when you are shutting down
and reenabling a cable interface:
Router# debug cr10k-rp ipc
CR10K RP debug IPC debugging is on
Router# configure terminal
Router(config)# interface c6/0/0
Router(config-if)# shutdown
schrp_cli_cmd: slot=6 subunit=100 slotunit=8 cmdtype=101F
c10k_card_send_nbcmd_eventrsp: nbcmd_id=0x611CE998 hwidb=6B3DF60
plugin_card__c10k_sch_card_event: hwidb=0x6B3DF60 interface_num=0 event=4096
sch_handle_sch_event: erso_type=0x1001
sch_handle_sch_rp_cfg_ersp(): hwidb=0x6B3DF60 msg_size=0x0 0x78
type=0x1001
plugin_card__c10k_sch_card_event: hwidb=0x6B3DF60 interface_num=0 event=4
c10k_sch_link_state_event: hwidb=0x6B3DF60 unit=0 seq=34 reason=2 event_state=1
Router(config-if)# no shutdown
Router(config-if)#schrp_cli_cmd: slot=6 subunit=100 slotunit=8 cmdtype=101F
schrp_cli_cmd: SCH_API_CMD_GET_INIT_DS hwidb=6B3DF60
c10k_card_send_nbcmd_eventrsp: nbcmd_id=0x611CE998 hwidb=6B3DF60
plugin_card__c10k_sch_card_event: hwidb=0x6B3DF60 interface_num=0 event=4096
sch_handle_sch_event: erso_type=0x1001
sch_handle_sch_rp_cfg_ersp(): hwidb=0x6B3DF60 msg_size=0x0 0x950
type=0x1001
c10k_card_send_nbcmd_eventrsp: nbcmd_id=0x611CE998 hwidb=6B3DF60
plugin_card__c10k_sch_card_event: hwidb=0x6B3DF60 interface_num=0 event=4096
sch_handle_sch_event: erso_type=0x1001
sch_handle_sch_rp_cfg_ersp(): hwidb=0x6B3DF60 msg_size=0x0 0x20
type=0x1001
plugin_card__c10k_sch_card_event: hwidb=0x6B3DF60 interface_num=0 event=4

The following example shows a typical display for the debug cr10k-rp pkt conditional command,
which displays packets for SID 2 on cable interface 6/1/0:
Router# debug cable interface c6/1/0 sid 2
Router# debug cr10k-rp pkt conditional
Router# show debug
CR10K PACKET:
Dump cr10k packets to/from RP conditionally
The following example shows how to enable conditional debugging of packets, displaying only those
packets that contain the desired mac address at byte 92 in the datagram:
Router# debug cr10k-rp pkt conditional peek 92
Router# debug cable interface c6/1/0 mac-address 00C0.abcd.ef00
Router# show debug
CR10K PACKET:
Dump cr10k packets to/from RP conditionally
Additionally, peeking inside transmitted pkts at offset 92
Both types of packet debugging generate output similar to the following example:
