DETAILED STEPS
Step 1
show platform hw-module-power
NoteEffective with Cisco IOS Releases 15.1(1)T and 15.0.1M(2), the Effective with Cisco IOS Releases 15.1(1)T and 15.0.1M(2), the hw-module energywise level command is not available in Cisco IOS software. For more information, see the Cisco 3900 Series, 2900 Series, and 1900 Series Software Configuration Guide.
Use this command to display power settings of PVDM3 service modules, for example:
Router# show platform hw-module-power Levels supported 0x441 : SHUT FRUGAL FULL CURRENT level : 10 (FULL) Previous level : 10 (FULL) Transitions : Successful Unsuccessful Levels supported 0x441 : SHUT FRUGAL FULL CURRENT level : 10 (FULL) Previous level : 0 (SHUT) Transitions : Successful Unsuccessful Levels supported 0x441 : SHUT FRUGAL FULL CURRENT level : 10 (FULL) Previous level : 10 (FULL) Transitions : Successful Unsuccessful Step 2 show voice call slot / port
Note If you are connected using a Telnet session, you must enter the terminal monitor command before the show voice call command to see console messages. This step is not necessary if you are connected to the console port.
Use this command to display statistics for voice calls on a specific slot and port, for example:
Router# show voice call 0/1/1:23 vtsp level 0 state = S_CONNECT callid 0x0011 B01 state S_TSP_CONNECT clld 4085001112 cllg 4085001112 vtsp level 0 state = S_CONNECT callid 0x0012 B02 state S_TSP_CONNECT clld 4085001112 cllg 4085001112 Step 3 show voice dsp group all
Use this command to display information for each DSP group, for example:
Router# show voice dsp group all State: UP, firmware: 26.0.135 Max signal/voice channel: 43/43 num_of_sig_chnls_allocated: 35 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 630, reserved credits: 0 Signaling channels allocated: 35 Voice channels allocated: 1 Credits used (rounded-up): 15 Ch01: voice port: 0/1/1:23.2, codec: g711alaw, credits allocated: 15 State: UP, firmware: 26.0.135 Max signal/voice channel: 43/43 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 645, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.135 Max signal/voice channel: 42/43 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 645, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.135 Max signal/voice channel: 43/43 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 645, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.135 Max signal/voice channel: 43/43 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 645, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.135 Max signal/voice channel: 42/43 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 645, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.135 Max signal/voice channel: 32/32 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 465, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 1 Credits used (rounded-up): 15 Ch01: voice port: 0/1/1:23.1, codec: g711alaw, credits allocated: 15 State: UP, firmware: 26.0.133 Max signal/voice channel: 16/16 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 240, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.133 Max signal/voice channel: 16/16 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 240, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.133 Max signal/voice channel: 16/16 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 240, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 State: UP, firmware: 26.0.133 Max signal/voice channel: 16/16 num_of_sig_chnls_allocated: 0 Transcoding channels allocated: 0 Group: FLEX_GROUP_VOICE, complexity: FLEX Shared credits: 240, reserved credits: 0 Signaling channels allocated: 0 Voice channels allocated: 0 Credits used (rounded-up): 0 This command is not applicable to slot 3 This command is not applicable to slot 4 2 DSP resource allocation failure Step 4 show voice dsp sorted-list
Use this command to display the hunt order in which DSPs are utilized for particular services (in this example, voice, conferencing, and transcoding are shown for slot 0):
Router# show voice dsp sorted-list slot 0 DSP id selection list for different service for Card 0: ======================================================== Voice :01,02,03,04,05,06,07 Conf :07,06,05,04,03,02,01 Xcode :01,02,03,04,05,06,07 Step 5 show voice dsp capabilities slot number dsp number
