I have configured the EPC in my CISCO 2901 CUBE for monitoring VOIP traffic.
#First I configure the type of traffic I want to filter access-list 110 permit tcp any any eq 5060 access-list 110 permit tcp any any eq 5061 access-list 110 permit udp any any eq 5060 access-list 110 permit udp any any eq 5061
# I apply the access-list to the buffer monitor capture buffer buff-SIP5 filter access-list 110 # Define the capture point, both interfaces, IN and OUT.. monitor capture point ip cef SIP5 all both #Associate capture point with buffer monitor capture point associate SIP5 buff-SIP5
#Start the capture monitor capture point start SIP5 #Stop it.. monitor capture point stop SIP5
#Check if you have what you need show monitor cap buffer buff-SIP5 dump
#Export it using scp monitor capture buffer buff-SIP5 export scp://email@example.com:/SIP5.pcap
I would like some help with these two issues:
1) When I export it, my pcap file is empty...yet when I do a dump, I can see everything I need
2) If I don't apply the access-list filter, I can see the SIP messages in the pcap file. However, I cannot see the messages that sends the SBC, only the ones that it receives.
1. Log into CLI of DNAC:
ssh maglev@< DNAC appliance IP> -p 2222
2. Run this curl command to get token to get member id:
curl -X POST -u admin:<admin user password> -H -V https://<CLUSTER-IP>/api/system/v1/identitymgmt/token
