Publication Date:  2015-04-14 Views:  76 Downloads:  3
Issue Description

VMs in some E9000 hosts can not get through the network, can't ping through the gateway.

Handling Process

1.VMs in some E9000 hosts can't ping through the gateway, but it can get through the gateway when it was migrated to another host, so it maybe the problem of switch of E9000.

2.Log on the XCUB of E9000, check the configuration of the problem hosts compared to nomoral hosts.

10GE 2/11/2  and 10GE 3/11/2 are the port of slot 11 connected to, this slot has no problem.

10GE 2/12/2  and 10GE 3/12/2 are the port of slot 1 connected to, this slot has network problem.

3.In the 10GE 2/12/2  and 10GE 3/12/2 ports, they didn't allowed vlan 114 to go through, and vlan 114 is the vlan of VMs.

4.Add the command of "port hybrid tagged vlan 114" and confirm in the port of 10GE 2/12/2  and 10GE 3/12/2.

Root Cause

 The E9000 equipped with 16 CH121 + MZ512 card and CX311 in the 2X-3X slot.

 In this case, the Port1 (eth0) and Port2 (eth1) of the CNA connect to 2/x/2 and 3/x/2,vlan 114 is the vlan which VMs used.

 the operator didn't allow the vlan 114 to go through in the eht0 and eth1,so it's the root reason.

Solution

Check all the configration of the XCUB in E9000, and make sure of the ports allowed the vlan 114 to go through.
