What is the meaning of the alarm "%Jan 25 10:58:07 2007 HALS-JM-R-NE40-01 RM/4/RMLOG: *
***Sending VLINK message to RM:: IfnetIdx = 1799, VlinkIdx = 107, PeerAddr = 126.96.36.199,
VLAN ID = 10, PhyOutIf = 0x4406, IfState = 0x1, Slot = 0, IfType = 0, MsgType = 0xFE" displayed by the device?
This log indicates that the system prompts this alarm for adding or deleting routes when the APR is added or deleted from a VLAN.
"MsgType = 0xFE" is a message of adding routes.
MsgType = 0xFD is a message of deleting routes.
"IfState = 0x1" indicates that the interface is Up.
"IfState = 0x2" indicates that the VLANIF interface is Down. At this time, the VLAN ID equals 0, which indicates that the VLAN ID need not be noted.
Reason for triggering:
If the system prompts this alarm for adding or deleting routes when the APR entry is added or deleted from a VLAN, it indicates that the device receives the ARP request or the message of deleting the ARP from the responded VLAN, the VLANIF interface is Up or Down, or the device is attacked by the ARP attacks.
Normally, on a stable network, frequent ARP learning and deletion cannot occur.
The alarm is normal and has no influence on the device. If the VLINK alarm frequently occurs in the log, it indicates that ARP oscillations occur on the user network or there are ARP attacks. Users need to optimize the network.
The alarm is normal and has no influence on the device. The device cannot avoid the alarm. Users need to optimize the network.
