1 This chapter provides the Cisco IOS XR commands to add the path protection profile and switch the traffic from working to protected path. Define the Working and Protecting Resources in an ODU Group Controller through Management Plane, page 1 Configure the Protection Attributes of an ODU Group Controller, page 2 Add a Path Protection Profile, page 3 Perform a Lockout, page 5 Perform a Forced Switch, page 6 Perform a Manual Switch, page 6 Define the Working and Protecting Resources in an ODU Group Controller through Management Plane Perform this task to define the working and protecting resources in an odu group controller through management plane. controller odu-group-mp group-id-of-the-controller signal {Ethernet FC OTN SDH Sonet} odu-type type-of-the-odu RP/0/RP0:hostname# controller odu-group-mp 5 signal OTN odu-type odu1 This creates the ODU group controller. The ODU Group MP value ranges from 1 to protecting-controller name-of-the-controller Rack/Slot/Instance/Port RP/0/RP0:hostname (config-odu-group-mp5)# protecting-controller odu1 0/0/0/
2 Configure the Protection Attributes of an ODU Group Controller Defines an ODUk (HO/LO) controller as the protecting resource in the ODU group controller. working-controller name-of-the-controller Rack/Slot/Instance/Port RP/0/RP0:hostname (config-odu-group-mp5)# working-controller odu1 0/0/0/1 Defines an ODUk (HO/LO) controller as the working resource in the ODU group controller. Step 5 Define Working and Protecting Resources in an ODU Group Controller The following example defines working and protecting resources in the ODU group controller using Cisco IOS XR commands: RP/0/RP0:hostname# terminal RP/0/RP0:hostname# controller odu-group-mp 5 signal otn odu-type odu1 RP/0/RP0:hostname(config-odu-group-mp5)# protecting-controller odu1 0/0/0/1 RP/0/RP0:hostname(config-odu-group-mp5)# working-controller odu1 0/0/0/1 RP/0/RP0:hostname(config-odu-group-mp5)#exit Configure the Protection Attributes of an ODU Group Controller Perform this task to the protection attributes of an odu group controller. controller odu-group-mp group-id-of-the-controller signal {Ethernet FC OTN SDH Sonet} odu-type type-of-the-odu RP/0/RP0:hostname# controller odu-group-mp 5 signal OTN odu-type odu1 This creates the ODU group controller. The ODU Group MP value ranges from 1 to protection-attributes {connection-mode protection-mode protection-type timers} SNC mode-of-the-protection-attributes RP/0/RP0:hostname (config-odu-group-mp5)# protection-attributes connection-mode snc-i Configures the connection mode of all the protecting resources in the ODU group controller. You can the connection mode as SNC/I, SNC/N, or SNC/S. protection-attributes {connection-mode protection-mode protection-type timers} mode-of-the-protection-attributes RP/0/RP0:hostname (config-odu-group-mp5)# protection-attributes protection-mode revertive wait-to-restore-time
3 Add a Path Protection Profile RP/0/RP0:hostname (config-odu-group-mp5)# protection-attributes protection-mode nonrevertive Configures the protection mode of all the protecting resources in the ODU group controller. You can the protection mode as revertive or non revertive. The value of wait-to-restore-time ranges from 300 to 720 seconds and default value is 300 seconds. Step 5 protection-attributes {connection-mode protection-mode protection-type timers} type-of-the-protection-attributes RP/0/RP0:hostname (config-odu-group-mp5)# protection-attributes protection-type APSuni Configures the protection type of all the protecting resources in the ODU group controller. You can the protection type as 1+1 bidirectional APS, 1+1 unidirectional APS or 1+1 no APS. Step 6 protection-attributes {connection-mode protection-mode protection-type timers} hold-off time timer-of-the-protection-attributes RP/0/RP0:hostname (config-odu-group-mp5)# protection-attributes timers hold-off-time 100 Configures hold-off timer for the ODU group controller. The valid range for the hold-off timer is from 100 to seconds. Step 7 Configure Protection Attributes of an ODU Group Controller The following example shows protection attributes of an ODU group using Cisco IOS XR commands: RP/0/RP0:hostname# terminal RP/0/RP0:hostname# controller odu-group-mp 5 RP/0/RP0:hostname(config-odu-group-mp5)# protection-attributes connection-mode snc-i RP/0/RP0:hostname(config-odu-group-mp5)# protection-attributes protection-type APSuni RP/0/RP0:hostname(config-odu-group-mp5)# protection-attributes protection-mode revertive wait-to-restore-time 300 RP/0/RP0:hostname(config-odu-group-mp5)# protection-attributes timers hold-off-time 100 RP/0/RP0:hostname(config-te-gmpls-tun-0x7)# Add a Path Protection Profile Perform this task to add a path protection profile. mpls traffic-eng RP/0/RP0:hostname (config)# mpls traffic-eng Enters the MPLS traffic-eng configuration mode. attribute-set {auto-backup auto-mesh p2mp-te path-option path-protection-aps xro} name-of-the-path-protection-aps
4 Add a Path Protection Profile RP/0/RP0:hostname (config-mpls-te)# attribute-set path-protection-aps abc Specifies the attribute set name. The maximum length for attribute set name is 32 characters. sub-network connection-mode {SNC-I SNC-N SNC-S} RP/0/RP0:hostname (config-te-attribute-set)# sub-network connection-mode SNC-N Specifies the sub-network connection mode. Step 5 protection-type {1-plus-1-BDIR-APS a-plus-1-unidir-aps 1-plus-1-UNIDIR-NO-APS} RP/0/RP0:hostname (config-te-attribute-set)# protection-type 1-plus-1-BDIR-APS Specifies the protection type. Step 6 protection-mode mode-of-the-protection RP/0/RP0:hostname (config-te-attribute-set)# protection-mode revertive Specifies the protection mode. Step 7 timers [hold-off wait-to-restore] RP/0/RP0:hostname (config-te-attribute-set)# timers hold-off 350 Specifies the timers value in seconds. The value of hold-off timer ranges from 100 to seconds. The value for wait to restore timer ranges from 300 to 720 seconds. Step 8 exit RP/0/RP0:hostname (config-mpls-attribute-set)# exit Exits the attribute set mode. Step 9 gmpls nni RP/0/RP0:hostname (config-mpls-te)# gmpls nni Enters the GMPLS NNI mode. 0 controller odu-group-te tunnel-id RP/0/RP0:hostname (config-te-gmpls-nni)# controller Odu-Group-Te 7 Specifies the tunnel ID. The value ranges from 0 to path-protection attribute-set name-of-the-path-protection attribute-set
5 Perform a Lockout RP/0/RP0:hostname (config-te-gmpls-tun-0x7)# path-protection attribute-set abc1 Specifies the attribute set name. The maximum length for attribute set name is 32 characters. 2 Add a Path Protection Profile The following example shows how to add a path protection profile using Cisco IOS XR commands: RP/0/RP0:hostname# terminal RP/0/RP0:hostname# mpls traffic-eng RP/0/RP0:hostname(config-mpls-te)# attribute-set path-protection-aps abc RP/0/RP0:hostname(config-te-attribute-set)# sub-network connection-mode SNC-N RP/0/RP0:hostname(config-te-attribute-set)# protection-type 1-plus-1-BDIR-APS RP/0/RP0:hostname(config-te-attribute-set)# protection-mode revertive RP/0/RP0:hostname(config-te-attribute-set)# timers hold-off 350 RP/0/RP0:hostname(config-te-attribute-set)# exit RP/0/RP0:hostname(config-mpls-te)# gmpls nni RP/0/RP0:hostname(config-te-gmpls-nni)# controller Odu-Group-Te 7 RP/0/RP0:hostname(config-te-gmpls-tun-0x7)# path-protection attribute-set abc1 RP/0/RP0:hostname(config-te-gmpls-tun-0x7)# Perform a Lockout Perform this task to perform a lockout. controller odu-group-mp group id-of-the-controller RP/0/RP0:hostname (config)# controller odu-group-mp 1 Enters the ODU group controller mode. protection-switching operate lockout odu-dest name-of-the-controllerrack/slot/instance/port RP/0/RP0:hostname (config-odu-group-mp1)# protection-switching operate lockout odu-dest odu0 0/0/0/0 Configures an ODUk controller as a locked out resource in the ODU group controller
