Hi all,
I have a problem with 4503 switch
I have 7 highend servers in my lan i.e 5hp and 2dell servers.
Each server has 4 network interface cards(1g). so 7*4=28 ports.
I have create vlan 70, ip add is 10.70.70.1
I have assign ip address to servers like
first server 10.70.70.2, 10.70.70.12,
Second server 10.70.70.3, 10.70.70.13,
Third server 10.70.70.4, 10.70.70.14,
fourth Server 10.70.70.5, 10.70.70.15, 10.70.70.25, 10.70.70.35
fifth server 10.70.70.6, 10.70.70.16, 10.70.70.26, 10.70.70.36
sixth server 10.70.70.7, 10.70.70.17, 10.70.70.27, 10.70.70.37
seventh server 10.70.70.8, 10.70.70.18, 10.70.70.28, 10.70.70.38
The problem is in four interfaces each server, only one or two interfaces are pinging, remaining interface are not pinging.
for example in the first server i can able to ping 10.70.70.12- macid 60eb.69d2.a2aa
i can't able to ping 10.70.70.2- macid 60eb.69d2.a2ab
second, fourth, fifth, sixth, and seventh continiously pinging successfully.
for example in fourth server i can able to ping 10.70.70.5 macid -b499.bafe.9c98
i can able to ping 10.70.70.15 macid-b499.bafe.9c98
i can able to ping 10.70.70.25 macid-b499.bafe.9c98
i can able to ping 10.70.70.35 macid-b499.bafe.9c98
now you understand what is the problem, which server i am not getting pinging that arp table shows each interface separte mac address
which server i am getting pinging that arp table shows each interface bind with same mac address(dynamically)
Please give me the solution

Hi,
I Think you need to do Teaming on the servers.
++ configure etherchannel between switch and the server.
configuring etherchannel b/w 4503 and server:
================================
http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a008089a821.shtml
Sample NIC Teaming - HP NICs with Cisco Switches (EtherChannel) :
==============================================
http://support.citrix.com/article/CTX434260
There are several NIC teaming technologies available today from switch vendors. Cisco uses the term “EtherChannel.” Various switch vendors use various terms, and these may or may not provide the same exact functionality. Use of EtherChannel technology requires support from the server hardware vendor, NIC vendor, and Layer-2 switch vendor.
Hope this helps
Cheers

please provide from the 4503
show mac-address table dynamic
show mac-address table static
show arp
please provide from one of the hosts
show arp
confirm the host is binding all the IP addresses to all the interface mac address
