SummarySome key information to know before installing a new expansion bridge card
OverviewExpansion NICs can be purchased in order to create more bridge pairs on the Exinda, in order to pass more (or different) traffic through the device. Many Exinda appliances have this upgradable capability, including the 4061, 6060, 6062, 8062, 8063, 10062 and 10063.
Installing the NIC is the same procedure as installing a PCI card in any server, as it uses the same connection. Each individual chassis might have slightly different methods in order to remove or add a NIC in (such as moving risers, taking care of screws and other hardware, etc). If unsure how to proceed with a bridge card installation, contact Exinda TAC for step by step documentation for the unit in question.
Once the NIC is installed, if the card is installed 'right side up' - that is, the text on the card is legible and readable when looking at it from the back - then the LAN port of a bridge pair will always be on the left hand side, and the WAN on the right. If in a case where the card has multiple bridges, the convention is that the left most port is the LAN of the first bridge, followed by the WAN of the first bridge, the LAN of the second bridge, etc. If the card is reversed - text is upside down when attempting to read it - then the convention is reversed.
After installing the bridge card and powering on the Exinda, if everything is in working order, the appliance will recognize the new ports and the new bridges automatically, without any user intervention. Checking the web UI under Configuration > System > Network will show the currently active ports and bridges that the appliance sees. Make sure you Speed, Duplex and MTU are configured and have their respective values, If any of the settings is missing then physical NIC port will keep flashing orange light.
The only device configuration that will depend on a bridge specifically is if a Circuit in the optimizer is tied to a bridge specifically (ie, if Circuit 10 is for traffic going over br10). If there is no Circuit tied to a specific bridge, the device needs no reconfiguration to work once the new NIC is installed, and will work as is.
From the CLI, this action can be done through a 'show interfaces' command, which will then list out all the interfaces in the device. Note, however, that 'show interfaces' will also show all bridges that have existed on the system, even if they do not currently exist. That means if one expansion card is changed for another, and the previous one had more bridges, the 'show interfaces' command will show the bridges for the previously existing bridges. To verify that the system is only currently seeing one card, examine the following:
- The corresponding ethernet ports for the bridges that do not exist anymore (in the case of bridge 20, it would be eth20 and eth21 for example) will not show up
- The bridges that do not exist anymore should have no traffic (no RX bytes, no TX bytes). These counters are cleared on a reboot, and after an installation of a new card, there will be a new boot. These counters should stay permanently at zero
If the bridge does not come up after an installation, consult with Exinda TAC for troubleshooting.
