Cannot change the speed for the interface.

Issue/Introduction

Unable to change the speed for the interface on the SSP box.

Resolution

The SSP appliance is shipped with an onboard network interface (0:0) and one or more additional Network Interface Cards (NIC). All applications that are created and started on the ISG by the 

applications

 commands share these physical interfaces. The following depicts an ISG shipped with a 4-port NIC that has one ProxySG and one Content Analysis application running.

You can find the MAC addresses for the physical interfaces by using the below ISG CLI  command:

#show hardware-configuration

Since all interfaces (physical and virtually mapped) have a unique L2 endpoint identifier (MAC address), you should use general networking approaches along with the following notes to work with applications deployed on ISG:

The physical link state of the SSP appliance is not mirrored to the running applications. Specifically, applications running on ISG always show every interface as being UP, even if the physical interface is DOWN, and the applications' reporting of link speed is independent of the physically set link speed on the SSP appliance.

Interface 0:0 is 1 Gbps.

• It is not recommended to use interface 0:0 for inter-application networking as it is limited to 1Gbps.
• It is not recommended to configure two or more of the physical interfaces on the same sub-network.
• It is not recommended to configure two or more of the virtual interfaces on a single application on the same sub-network.
• It is not possible to use the ISG CLI ping command to test connectivity between the ISG host and an application over the same shared physical interface unless hair-pinning mode is enabled in the upstream switch.

Applications receive broadcast, unicast, and Layer 2 multicast traffic.

LACP is supported and is configured from the ISG CLI.
