Home > Storage > Data Storage Essentials > Storage Resource Manager (SRM) > Dell SRM Data Forwarder > Validate communication from the frontend admin UI to the collector servers
In the frontend Admin UI, select /Config/Settings/Configure Servers and add the server configuration. Replace FRONTEND-IP, GATE-HOSTNAME, GATE-IP, and REMOTE-COLLECTOR-IP with the actual hostnames or IP addresses of the SRM servers.
Validate incoming packets on the REMOTE-COLLECTOR server:
REMOTE-COLLECTOR:~ # tcpdump -i any '(dst REMOTE-COLLECTOR-IP && dst port 48443) or (src REMOTE-COLLECTOR-IP && src port 48443)' -n
00:47:04.476831 IP FRONTEND-IP.59418 > REMOTE-COLLECTOR-IP.48443: Flags [S], seq 937714845, win 29200, options [mss 1460,sackOK,TS val 1512083573 ecr 0,nop,wscale 7], length 0
00:47:04.476944 IP REMOTE-COLLECTOR-IP.48443 > FRONTEND-IP.59418: Flags [S.], seq 3936610070, ack 937714846, win 28960, options [mss 1460,sackOK,TS val 1689190571 ecr 1512083573,nop,wscale 7], length 0
Repeat the steps for each other remote collector by specifying same gate hostname and a different port number (48444-48453, if there are 10 collectors).
