Before Establish SIC on Management ensure that your gateway CDP process is running cpwd_admin list
.The Gateway must have CPD running in E Stat .. to validate it, you can run cpwd_admin list if it is a T stat, you will not be able to establish SIC

Troubleshooting
if you build a new gateway and wants to test connectivity across the interfaces and the ping test does not work, do the following:
[Expert@myfw-fwa:# fw unloadlocal
[Expert@myfw-fwa:# cpstop
[Expert@myfw-fwa:# sbin/sysctl -w net.ipv4.ip_forward=1
fw monitor | grep 100.210.7.250
fw ctl zdebug + drop > text.drops
fw ctl zdebug + drop | grep 200.105.57.69
tcpdump -ni eth8 src 172.60.25.132
tcpdump -i eth1 port 1089 and dst 215.118.184.254
netstat -rn |grep 204.105
What happening to the traffic.
From expert mode on the Active Firewall:
fwaccel off Turn off SecureXL, if enabled)
df -h (Check for sufficient diskspace capture and debug_
fw monitor -o /var/log/fwmon.cap (In one session: Run the capture.)
fw ctl zdebug drop > /var/log/drop.txt (In another session: Run the kernel debug for drops.)
tcpdump -nnei any -w /var/log/tcp.cap (In a third session: Run a tcpdump capture.)
Re-create the problem.
Control-C (End the fw monitor, tcpdump and the kernel debug with the following:)
fwaccel on (Turn on SecureXL, if you disabled it)

RE: Traffic failing between internet Clusters
Run a packet capture and a kernel debug on the firewall so I can get a packet-level look at what is happening to the traffic.
From expert mode on the Active Firewall:
1. # fwaccel off (Turn off SecureXL, if enabled)
2. # df -h (Check your disk space to make sure you have sufficient space to run a capture and debug_
3. # fw monitor -o /var/log/fwmon.cap (In one session: Run the capture.)
4. # fw ctl zdebug drop > /var/log/drop.txt (In another session: Run the kernel debug for drops.)
5. # tcpdump -nnei any -w /var/log/tcp.cap (In a third session: Run a tcpdump capture.)
6. Re-create the problem.
7. Control-C (End the fw monitor, tcpdump and the kernel debug with the following:)
8. # fwaccel on (Turn on SecureXL, if you disabled it)
