We are developoing Southbound Gateway integration with a third party SNMP trap sender - we have confirmed traps are landing on the Linux server via tcpdump on port 162, but we are not seeing the same traps processed on the VNM model within Spectrum.
- ip tables on the Linux OX blocking traffic on port 162
- the kernel sends traffic to the tcpdump before hitting iptables firewall, so traps will show in tcpdump but are still technically blocked by the internal firewall
Release : 10.4
Component : Spectrum Core / SpectroSERVER
Linux OS
1. To disable ip tables, log in as root:
$ systemctl stop firewalld
# service iptables stop
NOTE: You may need to reference documentation for your version of Linux for proper syntax to disable the internal firewall
