Failed to execute iptable cmd: ," CMD="iptables -A SSH_ALLOW_RULES error

Hi Mates,

After upgrading rseries F5 OS to 1.5.4, I observed the below error and I am unable to do SSH for my F5 OS machine version 1.5.4 from the network: 10.54.7.0/24. Rest all the networks are working fine and we are able to do SSH to the same F5 OS machine. Is it something that device was unable to update this entry into iptables. Do we have to manually re-configure this rule?
