<p>Problem (highlighted in red color below) in enabling chassis cluster on SRX 5800</p><p>Steps followed:</p><p>1. Connected the Cables for Control & Data link</p><p>2. Configured control interfaces.</p><p>On Node 0 set chassis cluster control-ports fpc 1 port 0</p><p>On Node 1 set chassis cluster control-ports fpc 1 port 0 ( Please note that I cant put fpc 13 port 0 here as it will not accept as slot 13 does not exists)</p><p>3. Now enabling chassis cluster.</p><p>On Node 0 set chassis cluster cluster-id 1 node 0 reboot</p><p>On Node 1 set chassis cluster cluster-id 1 node 1 reboot</p><p>4. After the reboot, login to Node 1</p><p>Now changing the control ports as below set chassis cluster control-ports fpc 13 port 0</p><p>After doing this control-port (link) immediately comes up. 5. Node 1 becomes the primary now</p><p>6. The Node 1 is sending Heartbeat packets but not receiving it.</p><p> primary:node1} root@SRX-5800I-FW2> show chassis cluster control-plane statistics Control link statistics: Control link 0: Heartbeat packets sent: 103 Heartbeat packets received: 0 Heartbeat packet errors: 0 Control link 1: Heartbeat packets sent: 0 Heartbeat packets received: 0 Heartbeat packet errors: 0 Fabric link statistics: Probes sent: 102 Probes received: 0 Probe errors: 0</p><p>{primary:node1} root@SRX-5800-FW2> show chassis cluster control-plane statistics Control link statistics: Control link 0: Heartbeat packets sent: 105 Heartbeat packets received: 0 Heartbeat packet errors: 0 Control link 1: Heartbeat packets sent: 0 Heartbeat packets received: 0 Heartbeat packet errors: 0 Fabric link statistics: Probes sent: 104 Probes received: 0 Probe errors: 0</p><p>7. Problem is that on Node 0, SPC in slot 1, it shows amber light on it however the port 0 on this SPC shows active (green color). Grey color shows that interface is up.</p><p>{hold:node0} root@SRX-5800-FW1> show interfaces terse Interface Admin Link Proto Local Remote dsc up up em0 up up em0.0 up up inet 129.16.0.1/2 tnp 0x1100004 em1 up up em1.0 up up inet 129.16.0.1/2 tnp 0x1100004 fxp0 up down fxp0.0 up down inet 10.155.4.84/29 gre up up ipip up up lo0 up up lo0.0 up up inet 127.0.0.1 --> 0/0 lo0.16384 up up inet 127.0.0.1 --> 0/0 lo0.16385 up up inet lsi up up mtun up up pimd up up pime up up tap up up </p><p>{hold:node0}</p><p>Another problem is that this node goes into hold state which is the initial state upon boot in which RE is prepares to join the cluster, which never happens</p><p>8.
