Managing Test Server Other Ethernet Tab

On the Test Server Administration window, use the Other Ethernet tab to modify the IP address, the address pool, Mask, # of IPs, DHCP, Auto, Enabled on Boot, Limit ETH MTU to 2K bytes (default = off), Hybrid (see Note below), Hybrid Type , Promiscuous, VLANs and VLAN ID Ranges, Disable V6 Route Advert and duplex settings for each of the test server's Ethernet test ports. IPv4 (ethn) and IPv6 (ethnv6) configurations for each interface are displayed on separate rows.

Interfaces — You can modify the IP address, the Mask, the starting Pool IP address, the number of IP addresses in the address pool (# of IPs), whether the physical interface is Enabled on Boot, and the speed and duplex settings for all of the physical interfaces.

The Other Ethernet tab now has a split pane, top/bottom. The new bottom half allows you to enable Limit ETH MTU to 2K bytes, Hybrid, Hybrid Type, Promiscuous, VLANs and VLAD ID ranges, Disable V6 Route Advert (Router Advertizement). The Interface/Port tables were improved to fully hide unused columns and to shade out unused cells depending upon the capabilities and options for a given Test Server.

DHCP - Select DHCP and Enable on Boot for request to DHCP server for test ports. After Applying the configuration and the Test Server Reboots and you re-open the Test Server configuration, the IP Address, Mask and Pool IP fields will be filled based on the reply by the DHCP server. DHCP feature is not supported on Aonic cards.

NOTEs:

If DHCP is successful, the original IP/MASK will be lost since the values will be replaced by the DHCP server. If you uncheck the DHCP checkbox after successful DHCP, the IP/MASK values will be cleared and the user will be required to enter static values.
If DHCP failed to get new values, the original / previous values will be preserved, Enable On Boot will be set to unchecked and DHCP will be left Checked. In addition, a new message will be added to the Error Tab, "DHCP Failed Ports : eth2, eth2v6". You can try to resolve the DHCP issue, then Select Enable On boot again and Apply to retry DHCP, or you can check Enabled on Boot and uncheck DHCP and after confirming correct static IP/MASK fields, Apply to return to static.
Hybrid Mode is not supported with DHCP. In addition, for ports with invalid lease , a new Warning message will be displayed " WARNING : DHCP with Possibly Invalid Leases, etc1".
A Warning message will indicate the default route in case it is needed for provisioning : " WARNING : Default gateway eth 15 [DHCP] is 10.71.31.1 ".

Enabled On Boot - A checkbox that defines whether the test port is enabled when the test server is rebooted. eth0 and eth1 cannot be Enabled on Boot as test ports on all physical test servers except E10s.
Limit ETH MTU to 2K bytes - When enabled, it provides additional memory for application usage. It also increases Landslide's capacity of temporary buffers therefore reducing the chance of message exhaustion. When used, it is enabled for all the ports on the selected Test Server. This option should only be enabled if:
- You know there will be no jumbo MTU greater than 2000 bytes.
- Test server does not have NIC_27 interface enabled.
Hybrid mode - Enabling this option overrides a port's user space driver with the kernel driver. Required for proper operation of a Landslide Virtual Test Server on the Xen Hypervisor. when enabled, you must select a Hybrid Type or you will get an error indicating " If Hybrid Mode is enabled, please select a Hybrid Type".
Hybrid Type - Options AF_PACKET, RAW_SOCKET, EXT_APP, NET_PCAP - When Hybrid Mode is enabled, you must select a DPDK driver (Hybrid Type). When not sure, please select AF_PACKET. AF_PACKET uses DPDK AF_PACKET poll mode driver which in turn uses kernel driver. Because it uses mmap it's performance should be better than traditional hybrid mode. RAW_SOCKET is the traditional hybrid mode. EXT_APP is for External Utility Node TC testing only. NET_PCAP enables eth port to use DPDK libpcap based poll mode driver. If you turn on Hybrid Mode for multiple ports they must all have the same Hybrid Type selected or you will get an error indicating "All Ports using Hybrid Mode must use the same Hybrid Type".

NOTEs: Hybrid Mode

Hybrid Mode uses DPDK memory management.
All IP addresses are managed by Landslide.
This allows the user to use large number of IPs (any number of IPs within subnet, same as Landslide in usermode) and also port reservation.
Packet is sent out using kernel driver (similar to kernel mode).
Hybrid mode is mostly used where landslide recognizes NIC in ethMapper but landslide DPDK does not support this NIC.
Hybrid mode can also be used to debug routing issues or supported NICs.
When enabled, you must select a Hybrid Type.
Both legacy mode and max mode are supported by AF_PACKET and RAW_SOCKET.
AF_PACKET supports Fireball and VLAN Configuration. RAW_SOCKET does NOT support Fireball or VLAN Configuration.
EXT_APP is used only in External Utility Node test case with twamp testing, for the port that exchanges packets with twamp container. Note this interface shall not be selected by any other test Node.

Promiscuous - Provides the ability to turn off Promiscuous Mode for Virtual Test Servers. This is only supported for user mode test servers. Select to enable Promiscuous Mode.
VLANs and VLAN ID Ranges - Provides the ability to configure VLAN ID Ranges on Virtual Test Servers for specific NIC Types only. VLAN ID Ranges can be single or ranges of IDs in sequential order, e.g. : 1, 5, 55-333, 999, 1031-1035. Limited to 64 VLAN IDs per Interface. Valid Range is 0 to 4095. You will receive error : " VLAN IDs item #n ID 5333 is not a valid VLAN ID between 0 and 4095" if you enter a number that does fall between 0 and 4095 as in this example where 5333 was used.
Disable V6 Route Advert - Select this option to disable V6 Router Advertisement for an incoming V6 Router Solicitation.
