Chapter 16 Configuring the Cisco Phone Proxy

Troubleshooting the Phone Proxy

The SAST keys can be seen via the show crypto key mypubkey rsa command. The SAST keys are associated with a trustpoint that is labeled _internal_ctl-file_name_SAST_Xwhere ctl-file-nameis the name of the CTL file instance that was configured, and X is an integer from 0 to N-1 where N is the number of SASTs configured for the CTL file (the default is 2).

Step 1 On the ASA, export all the SAST keys in PKCS-12 format by using the crypto ca export command:

hostname(config)# crypto ca export _internal_ctl-file_name_SAST_Xpkcs12 passphrase

hostname(config)# Exported pkcs12 follows: MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH

[snip]

MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH

---End - This line not part of the pkcs12---

hostname(config)# crypto ca export _internal_ctl-file_name_SAST_Xpkcs12 passphrase

hostname(config)# Exported pkcs12 follows: MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH

[snip]

mGF/hfDDNAICBAA=

---End - This line not part of the pkcs12---

hostname(config)#

Note Save this output somewhere secure.

Step 2 Import the SAST keys to a new ASA.

a.To import the SAST key, enter the following command:

hostname(config)# crypto ca import trustpoint pkcs12 passphrase

Where trustpoint is _internal_ctl-file_name_SAST_Xand ctl-file-nameis the name of the CTL file instance that was configured, and X is an integer from 0 to 4 depending on what you exported from the ASA.

b.Using the PKCS-12 output you saved in Step 1, enter the following command and paste the output when prompted:

hostname(config)# crypto ca import _internal_ctl-file_name_SAST_Xpkcs12 passphrase

hostname(config)# Enter the base 64 encoded pkcs12. hostname(config)# End with the word "quit" on a line by itself: MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH

[snip]

muMiZ6eClQICBAA= hostname(config)# quit

INFO: Import PKCS12 operation completed successfully

hostname(config)# crypto ca import _internal_ctl-file_name_SAST_Xpkcs12 passphrase

hostname(config)# Enter the base 64 encoded pkcs12. hostname(config)# End with the word "quit" on a line by itself: MIIGZwIBAzCCBiEGCSqGSIb3DQEHAaCCBhIEggYOMIIGCjCCBgYGCSqGSIb3DQEH
