Unable to access UCS ESXi5.0 U1 from outside network

Dear Cisco Experts,

Greeting for the day. I hope this email find your well and wishing you the same.

I have the below setup in my data center and trying to deploy VMWARE ESXi5.0 U1 on UCS and having some challenges to access my esxi from outside network. Please find the below details and help me to overcome from this issue

1) UCS chassis (1 x 5108)

2) M200 blades (2 blade have been installed and rest of the 6 slots are empty)

3) UCS2208XP IOM (2 IOM's)

4) UCS cisco fabric interconnect 6648 (2 interconnects)

5) MDS9124 cisco switch --> Exisiting fabric switch from our DC (only 1 switch/fabric, no redundancy)

6) Netapp V6080

7) Catalyst 2960 L2 switch.

From UCS chassis, 2 ports per IOM have been connected with each fabric interconnect and interconnects are clustered between them. From Interconnect i have connected 2 FC uplink port to my MDS 9124 switch.I have deployed vmware esxi5.0 u1 on both of my blades and created a VSAN from UCS and found that virtual HBA's are logged into fabric. Hence i have zonned with Netapp and registered with netapp, created some test lan.

From my Layer2 cisco 2960G switch, i have connected 2 network cables to my interconnects via GLC-T SFP ( 1 cabler per fabric interconnect) and placed those 2 ports vlan2 from cisco L2 switch. created same vlan from UCS and added my vNIC from UCS Servers.

From the L2 switch, my exisiting vmware cluster is running with 3 HP G7 servers and vcenter is running in virtuam machine. My Vcenter IP is:192.168.1.1/255.255.255.0 , my esxi servers are having ip ranges from 172.21.1.1-172.21.1.3 /255.255.255.0 (3 servers totally) and between these 2 networks communication has been allowed.

Question:

I would like to assign the same range of IP to my new ESXi servers which are running from 2 UCS blades. IP's are 172.21.1.10 & 172.21.1.11 /255.255.255.0. So that i can add these servers to my exisiting Vcenter and able to increase the resources but where as i am unable to ping the new esxi server from my network. May i know the reason why? Did i missed anything to configure? Did i not followed the best practise?

I would greately appreciate if anyone can able to help me to correct my configuration. As of now facing access problem to reach out my ESXi server from my network.Let me know if you need any additional information regarding this subject

FYI:-

interface GigabitEthernet0/21

switchport access vlan 2

switchport mode trunk

!

interface GigabitEthernet0/22

switchport access vlan 2

switchport mode trunk

Hello Suresh,

Assuming you created the VLANs on UCS and vNICs are associated with correct VLANID for vmkernel IP,

please re-configure the upstream 2960 switch port and let us know the outcome.

no switchport access vlan 2

switchport trunk native vlan 2

spanning-tree portfast trunk

If it still does not work, provide output of following commands

connect nxos a

show mac address-table

## 2960 switch

show mac address-table

Dear Padma,

Thank you for your immediate response. trunk and spanning tree have been configured and i have doubled checked the same. As per your request, please find the details:

Hello suresh,

Please check the MAC address of the vmkernel interface ( esxcfg-vmknic -l ) and verify they are learnt on the correct VLAN on both FI and 2960 switch.
