How to run URT bundle on ISE

URT bundle can be used to check if the upgrade will be successful or not.  We can fix the error and then can schedule a window to ugrade the ISE.

Step 1> Create a repository on the ISE node

Step 2> Download the URT bundle from ISE.

Step 3> Upload the URT bundle on repository.

Step 4> Run the URT bundle on secondary node or on standalone node.

application install <URT file name > <repository name>

If for some reason the URT fails it will create a file share that file with TAC for further troubleshooting.

Send ACL logs to syslog in ASA

If you want to log the traffic allowed by an ACL on ASA to syslog server.

Step 1> You need to create ACL and add log keyword in ACL entry

access-list vlan3-5 extended permit ip host host log debugging

Here I have used “log debugging” you can use as per your requirement.

Step 2> Configure ASA to send the logs to syslog server:

logging enable
logging timestamp
logging list syslogmsg message 106100
logging list syslogmsg message 302013
logging list syslogmsg message 302014
logging list syslogmsg message 302020
logging list syslogmsg message 302021
logging trap syslogmsg
logging host vlan3

302020 Build inbound ICMP
302021 Tear down ICMP
302013 Build inbound TCP
302014 Tear down TCP
302015 Build inbound UDP
302016 Tear down UDP

710003 TCP denied by ACL

Configuration backup CISCO ISE

This document explains how to take backup of configuration so that it can be used in case where ISE configuration needs to be restored. Backup can only be taken from primary node in case ISE is in deployment.  Taking configuration backup on ISE can take some couple of minutes to an hour. Backup can be taken from CLI or from GUI.

It is recommend to take configuration backup on external server (FTP,SFTP,TFTP…). Backup can also be take on ISE local disk.

Step 1> To take configuration backup you have to configure repository first. To configure repository use following link.

Backup can be scheduled or can be taken on demand. Administrator>System>Backup and restore

Step 2> Click on Backup now and specify the name of the backup file, Select Configuration as type and select the repository which you have just created. Give an encryption key. Encryption key will be used to encrypt the backup file.

Configuration backup GUI-4

Step 3> Backup the Internal CA store using CLI command. You have to give repository name which you just created.

Configuration backup GUI-7

Equivalent CLI command:

backup  repository  ise-config encryption-key plain
