Cluster Debug Notes

There are tons of these, but I wanted to keep my own copy from Sergei so I can update.

Enabling VMAC is not related to cluster failover
VMAC is intended to eliminate problems with ARP cache on L2/L3 networking devices

The issues with different values in ‘Required interfaces’ are solved in the following way :

A) make sure the configuration of interfaces is identical on all cluster members (i.e., pairs of interfaces are assigned the same subnet mask , the total number of interfaces is identical, etc)

NOTE: on GAIA you should double check the configuration – the outputs of ‘show interfaces’ in CLISH must match the outputs of ‘ifconfig’ in Expert mode

B) SmartDashboard – cluster object – ClusterXL – Topology – Edit
— get the interfaces with topology from each member
— configure VIP addresses
— OK
— File menu – Save

C) SmartDashboard – install policy onto cluster object

D) on each cluster member check that the policy was installed
# cpstat -f policy fw

E) reboot each member

F) output of ‘cphaprob -a if’ must be identical on all cluster members

If these outputs differ on cluster members, then it is necessary to collect the debug of cluster configuration from each member

# fw ctl debug 0
# fw ctl debug -buf 32000
# fw ctl debug -m cluster + conf stat pnote if

# fw ctl kdebug -T -f 1>> /var/log/$(uname -n)_cluster_debug.txt 2>> /var/log/$(uname -n)_cluster_debug.txt

Install policy in SmartDashboard

press CTRL+C
# fw ctl debug 0

Send for analysis
— CPinfo file from each member
— /var/log/HOSTNAME_cluster_debug.txt from each member
— /var/log/messag* from each member
— CPinfo file from MGMT Server

=====================  Mike Notes ========================

fw ctl zdebug -m fw + drop  SK80520

fw ctl zdebug -m cluster + select  SK35211


Super detailed CP clustering info



Enable/Disable Sync: fw ctl setsync start/stop

Life Stories from Dreez

These are stories from my travels. Generally I like to write stories about local people that I meet and also brag about living the retirement dream with my #1 wife Gaby. She is also my only wife.
