Cisco Unified Border Element (SP Edition) Configuration Guide: Unified Model

Step 1

configure

Router# configure

Enables global configuration mode.

Step 2

sbc service-name

Router(config)# sbc mysbc

Enters the mode of an SBC service.

Use the service-name argument to define the name of the service.

Step 3

sbe

Router(config-sbc)# sbe

Enters the mode of the signaling border element (SBE) function of the SBC.

Step 4

hold-media-timeout timeout

Router(config-sbc-sbe)# hold-media-timeout 7200

The time an SBE will wait after receiving a media timeout notification from the DBE for an on hold call before tearing that call down.

• When the DBE detects that media has stopped on a call, it will start a timer for the specified duration, using the DBE media timeout command line interface (CLI) command.
• If no media flows before this timer expires, then the DBE will send a pin-hole timeout event notification to the SBE.
• If the call is on hold, the SBE will set a timer with a duration matching the configured value using this command.
• If the call is not taken off hold before the SBE timer expires, then the call will be torn down.

The default value for this command is off. Unless a specific duration is set, on hold calls never time out.

Step 5

end

Router(config-sbc-sbe)# end

Exits the configuration session and enters Privileged EXEC mode.

Step 6

show sbc sbc-name sbe hold-media-timeout

Router# show sbc mysbc sbe hold-media-timeout

Shows the currently configured duration of the media timeout timer for on-hold calls.

Step 7

show sbc sbc-name sbe calls

Lists all the calls on the SBE.

Step 1

configure terminal

Router# configure terminal

Enables global configuration mode.

Step 2

sbc service-name

Router(config)# sbc mysbc

Enters the mode of an SBC service.

Use the service-name argument to define the name of the service.

Step 3

sbe

Router(config-sbc)# sbe

Enters the mode of the signaling border element (SBE) function of the SBC.

Step 4

cac-policy-set policy-set-id

Router(config-sbc-sbe)# cac-policy-set 1

Enters the submode of CAC policy set configuration within an SBE entity.

Step 5

first-cac-scope scope-name

Router(config-sbc-sbe-cacpolicy)# first-cac-scope global

Configures the scope at which to begin defining limits when performing the admission control stage of policy.

The scope-name argument configures the scope at which limits should be initially defined. Possible values are:

• adj-group
• call
• category
• dst-account
• dst-adj-group
• dst-adjacency
• dst-number
• global
• src-account
• src-adj-group
• src-adjacency
• src-number

Features can be enabled or disabled per adjacency group through CAC configuration the same way this is done per individual adjacencies.

Step 6

first-cac-table table-name

Router(config-sbc-sbe-cacpolicy)# first-cac-table RootCacTable

Configures the name of the first policy table to process when performing the admission control stage of policy.

Step 7

cac-table table-name

Enters the mode for configuration of an admission control table (creating one if necessary) within the context of an SBE policy set.

Step 8

table-type {policy-set | limit {list of limit tables}}

Router(config-sbc-sbe-cacpolicy-cactable)# table-type limit event-type

Configures the table type of a CAC table within the context of an SBE policy set.

list of limit tables can be one of the following values:

• account —Compare the name of the account.
• adj-group —Compare the name of the adjacency group.
• adjacency —Compare the name of the adjacency.
• all —No comparison type. All events match this type.
• call-priority —Compare with call priority.
• category —Compare the number analysis assigned category.
• dst-account —Compare the name of the destination account.
• dst-adj-group —Compare the name of the destination adjacency group.
• dst-adjacency —Compare the name of the destination adjacency.
• dst-prefix —Compare the beginning of the dialed digit string.
• event-type —Compare with CAC policy event types.
• src-account —Compare the name of the source account.
• src-adj-group —Compare the name of the source adjacency group.
• src-adjacency —Compare the name of the source adjacency.
• src-prefix —Compare the beginning of the calling number string.

Features can be enabled or disabled per adjacency group through CAC configuration the same way this is done per individual adjacencies. The adj-group table type matches on either source or destination adjacency group.

Step 9

entry entry-id

Creates or modifies an entry in a table.

Step 10

cac-scope { list of scope options }

Router(config-sbc-sbe-cacpolicy-cactable-entry)# cac-scope call

Configures the scope within each of the entries at which limits are applied in a policy set table.

• list of scope options—Specifies one of the following strings used to match events:

– account —Events that are from the same account.

– adjacency —Events that are from the same adjacency.

– adj-group —Events that are from members of the same adjacency group.

– call —Scope limits are per single call.

– category —Events that have same category.

– dst-account —Events that are sent to the same account.

– dst-adj-group —Events that are sent to the same adjacency group.

– dst-adjacency —Events that are sent to the same adjacency.

– dst-number —Events that have same destination.

– global —Scope limits are global

– src-account —Events that are from the same account.

– src-adj-group —Events that are from the same adjacency group.

– src-adjacency —Events that are from the same adjacency.

– src-number —Events that have the same source number.

– sub-category —The limits specified in this scope apply to all events sent to or received from members of the same subscriber category.

– sub-category-pfx —The limits specified in this scope apply to all events sent to or received from members of the same subscriber category prefix.

– subscriber —The limits specified in this scope apply to all events sent to or received from individual subscribers (a device that is registered with a Registrar server).

Step 11

match-value key

Router(config-sbc-sbe-cacpolicy-cactable-entry)# match-value call-update

Specifies the keyword used to match events. The format of the key is determined by the table-type. If you configure either an event-type or call-priority Limit table, then you only see the keyword options that apply for that type of Limit table.

For Limit event-type tables (table-type limit event-type), the match value keyword options are the following:

• call-update—Compare the beginning of the calling number string.
• endpoint-reg—Compare the name of the destination adjacency.
• new-call—Compare the beginning of the dialed digit string.

For Limit call-priority tables (table-type limit call-priority), the match value keyword options are the following:

• critical—Match calls with resource priority ‘critical.’
• flash—Match calls with resource priority 'flash'.
• flash-override—Match calls with resource priority ‘flash-override.’
• immediate—Match calls with resource priority ‘immediate.’
• priority—Match calls with resource priority ‘priority.’
• routine—Match calls with resource priority ‘routine.’

For all other Limit tables, enter a name or digit string.

WORD—Name or digit string to match. (Max Size 255).

Step 12

caller-hold-setting {hold-c0 | hold-c0-inactive | hold-c0-sendonly | hold-sendonly | standard}

Configures the caller hold settings that are supported.

Step 13

action [cac-complete | next-table goto-table-name ]

Specifies the action to take if this routing entry is chosen.

Step 14

exit

Router(config-sbc-sbe-cacpolicy-cactable-entry)# exit

Exits the cactable entry configuration mode and enters the cactable mode.

Step 15

exit

Router(config-sbc-sbe-cacpolicy-cactable)# exit

Exits the cactable configuration mode and enters the cacpolicy mode.

Step 16

complete

Completes the CAC-policy or call-policy set after committing the full set.

Step 17

active-cac-policy-set policy-set-id

Sets the active CAC-policy-set within an SBE entity.
