Improper configuration of the NICs used for the VMware Channel connection
ISP problems in a WAN environment
Resolution
When a NIC problem is encountered, the following should be checked.
Verify that VMware Channel NIC drivers are the correct and latest versions. Known issues are identified
with HP/Compaq ProLiant NC67xx/NC77xx Gigabit Ethernet NICs. Check other NIC types. See
knowledge base article 1008383 (vCSHB-Ref-116) – VMware vCenter Server Heartbeat and Gigabit Ethernet
NIC drivers. (NC77XX).
Verify hubs and Ethernet switches are operating properly. Identify and replace any defective
components.
Test for defective Ethernet patch or crossover cables and replace if defective.
Correctly configure the NICs used for the VMware Channel connection.
Check the physical link for ISP problems.
Firewall Connection
In a LAN or WAN deployment, the VMware Channel can be connected through one or more Internet firewalls.
Because firewalls block unauthorized network traffic, configure firewalls on the route of the VMware Channel
to allow channel traffic.
Symptoms
The VMware Channel cannot connect, or continuously connects and disconnects.
Causes
In a WAN deployment, port 57348 or any other port configured for the VMware Channel is closed on one or
more firewalls on the route between the VMware Channel NIC on the Primary server and its counterpart on
the Secondary server.
Resolution
Open port 57348 and any other port configured for the VMware Channel on all firewalls on the route between
the VMware Channel NIC on the Primary server and its counterpart on the Secondary server.
Incorrect VMware Channel Configuration
An incorrectly configured channel connection can prevent proper communication and replication.
Symptoms
The following problems are experienced:
IP conflicts occur on one of the VMware Channel IP addresses
The VMware Channel does not connect, or connects and disconnects
Causes
The list below provides the most common misconfigurations.
Identical IP addresses at each end of the VMware Channel
IP addresses in different subnets without static routing at each end of the VMware Channel
VMware Channel NIC configured for DHCP when a DHCP server is not available
