Troubleshooting VFP and VCP Connection Establishment
Purpose
When the VCP and VFP connection is established, the show interfaces terse command in the VCP CLI displays the ge-0/0/x interfaces and the following messages appear in the
VFP syslog file:
RPIO: Accepted connection from 128.0.0.1:50896 <-> vPFE:3000 RPIO: Accepted connection from 128.0.0.1:56098 <-> vPFE:3000 HOSTIF: Accepted connection
If the VCP cannot connect to the VFP, the VFP syslog file does
not display the RPIO and HOSTIF messages.
Action
Run the request chassis fpc slot 0 restart command from the VCP CLI to restart the FPC. If an FPC is in transition error message is displayed, then
run restart chassis-control.
If these commands do not correct the problem, verify whether
the VCP can ping the VFP from the routing-instance __juniper_private1__. The three management interfaces (for the host, VCP VM, and VFP
VM) connected to the internal bridge should be able to reach each
other. For example:
root> ping 128.0.0.16 routing-instance __juniper_private1__ PING 128.0.0.16 (128.0.0.16): 56 data bytes 64 bytes from 128.0.0.16: icmp_seq=0 ttl=64 time=0.273 ms 64 bytes from 128.0.0.16: icmp_seq=1 ttl=64 time=0.606 ms
If the VCP cannot ping the VFP, perform these tasks:
Make sure that both the VCP and VFP have the network adapter connected to the internal bridge vSwitch (br-int).
Verify that the MAC address of em1 on the VCP matches the MAC address shown in the Virtual Machine Properties.
To determine the MAC address of the em1 interface:
content_copy zoom_out_maproot@% ifconfig em1 | grep "curr media" | awk '{print $NF}'Verify that the MAC address of the interface on the VFP matches the MAC address shown in the Virtual Machine Properties.
To determine the MAC address of the interface:
content_copy zoom_out_maproot@localhost:/var/log# ifconfig int | grep "HWaddr" | awk '{print $NF}'
If the problem persists, contact the Juniper Networks Technical Assistance Center (JTAC).
