Hi,

ICMP port unreachable in genral means an error (the designated protocol is unable to inform the host of the incoming message),but check out the below link on solaris paltform for icmp port unreeachable messages.

Hi Senthil,

When a datagram is dropped due to expiration of the TTL field, the device that dropped the datagram will inform the source of this occurrence by sending it an ICMPv4 Time Exceeded message,Receipt of this message indicates to the original sending device that there is either a routing problem when sending to that particular destination, or that it set the TTL field value too low in the first place. As with all ICMP messages, the device receiving it must decide whether and how to respond to receipt of the message. For example, it may first try to re-send the datagram with a higher TTL value.

Is the same message coming from your huwei routers also when you ping the 4507 gateway ip address and what is the configurtion in 4507 you have !!

Hope to Help !!

Sir,

error messages are not coming While pinging 10.40.250.3 from Huawei switches.

Configuration of 4507 switch is

int vlan 1

ip address 10.40.250.3

int vlan 2

ip address 10.40.25.154

int giga3/25

switch port access vlan 2

Hi Senthil,

As per the configuration if port 3/25 of ciso 4507 is connected to Huawei router inetrface,then either configure this port as access port or trunk port,so for configuring the trunk check out the below link for the same or remove trunk and then check is ping is breaking intermittently.
