Verifying the Router, Cisco SRE Service Module, and Cisco IOS Software Version Compatibility

For all Cisco router models (2911, 2921, 2951, 3925, 3925e, 3945, and 3945e), and for all versions of the Cisco SRE Service Module (700, 710, 900, and 910), the Cisco IOS software version that you must install on the router, in order to use Cisco SRE-V, is Release 15.1(4) M or later.

Installing the Cisco SRE Service Module into the Router

To install the Cisco SRE Service Module into the Cisco 2900 series or 3900 series ISR G2, see Figure 2-1. For detailed information, see Installing Cisco Network Modules and Service Modules in Cisco Access Routers.

Caution Before you install or remove the Cisco SRE Service Module from a Cisco 2900 series ISR G2, make sure that you first power down the router.

Verifying the Cisco SRE Service Module Installation

After the Cisco SRE Service Module is physically installed into a Cisco router, the router is loaded with a compatible Cisco IOS image, and the router is powered back on, do the following to ensure that the Cisco SRE Service Module is correctly detected by the router.

Procedure


Step 1 From the router, enter enable to go into enable mode.

Step 2 Enter the show diag | include FRU command.

The system displays the Field Replaceable Unit (FRU) details, as shown in the following example of a Cisco SRE 900 Service Module:

Router# show diag | include FRU
		Product (FRU) Number     : CISCO2951/K9
		Product (FRU) Number     : PWR-2921-51-POE
		Product (FRU) Number     : PVDM3-32
		Product (FRU) Number     : SM-SRE-900-K9
 
   

Step 3 Use the show hardware command to verify that the router recognizes the service module.

Online Insertion and Removal of the Cisco SRE Service Module


Note Only the Cisco 3900 series ISR G2 supports the Online Insertion and Removal (OIR), or hot swap, of the Cisco SRE Service Module.

The Cisco 2900 series ISR G2 does not support the OIR of the Cisco SRE Service Module.


To perform the OIR of a Cisco SRE Service Module from a Cisco 3900 series ISR G2, complete the following steps.

PREREQUISITES

You cannot perform the OIR of a Cisco SRE Service Module when the VMware vSphere Hypervisor is in lockdown mode. If you enter the service-module sm slot/0 shutdown command when the VMware vSphere Hypervisor is in lockdown mode, the system moves the Cisco SRE Service Module to shutdown state but the VMware vSphere Hypervisor does not shut down. In addition, the system cannot process any subsequent service-module sm slot/0 commands. To recover from this, reset the Cisco SRE Service Module.

For more information about lockdown mode, see the "About Lockdown Mode" section.

SUMMARY STEPS

1. service-module sm slot/0 shutdown

2. service-module sm slot/0 status

3. hw-module sm 1 oir-stop

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

service-module sm slot/0 shutdown

Example:

Router# service-module sm 1/0 shutdown

Shuts down the Cisco SRE Service Module system gracefully. Use this command when removing or replacing a hot-swappable module during OIR.

If the virtual machines on the VMware vSphere Hypervisor have VMware tools installed on them, and you issue this command, the virtual machines shut down first, and then the Cisco SRE Service Module shuts down.

If the virtual machines do not have VMware tools installed on them and you issue this command, the virtual machines power off first, and then the shutdown signal is sent to the service module. After about two minutes, the Cisco SRE Service Module shuts down.

Note The system does not support the service-module sm slot/0 shutdown command when the VMware vSphere Hypervisor is in lockdown mode.

Step 2 

service-module sm slot/0 status

Example:

Router# service-module sm 1/0 status

Verifies whether the Cisco SRE Service Module system is in the shut down state.

Step 3 

hw-module sm 1 oir-stop

Example:

Router# hw-module sm 1 oir-stop

Removes the Cisco SRE Service Module from the router.

When you enter this command, OIR messages are displayed. After the messages finish displaying, remove the Cisco SRE Service Module from the router.
