Chapter 3 High Availability Networkin g High availability networking is achieve d by eliminating any single point of failure through redundant connectivity: Redundant cable s, switches and network interfaces for hardware, combined with HA software solutions on both the hos ts and switches to control the HA hardware and maintain connectivity. An HA [...]

VRRP Since most end nodes use default router addres ses, the change of the default router address during a switch failover would require the end nodes to reconfigure. Layer 3 switches that failover must maintain the default router address to ma intain the end node's IP transparent failover. The Vi rtual Router Redundancy Protocol (VRRP, RFC 23[...]

Switch Replacement and Reconf iguration When a switch fails, it must be repl aced. The replacement switch will likely requi re proper configuration. For transparent switch replac ement, the newly replaced switch must le arn its configuration from its Surviving Partner. In a simple failover scenario, Host A a nd Host B are configured with failover b[...]

The configuration and runtime scripts creat ed are as follows: • S70Surviving_partner Switch initialization script that is run at boot time. This script will restart the switc h with the original configuration given to zspconfig . Optionally, zspconfig will run this script from the i nitial invocation. • zsp.conf.<n> - zspconfig configura[...]

When using a Linux Bonding driver on the node card, the bonding dri ver should be configured for Mode 1 (active/standby). See the Linux Bonding docum entation at http://sourceforge.net/project s/bonding/ for complete information. The two Base switches will be configure d as Surviving Partners, using VRRP to form a single virtual interface to the ho[...]

We are going to create a virtual interface across one VLAN, but not for the inte rconnect. This provides a single point to connect/route to the VLANs. vrrp_virtual_address: zhp1 = 10.0.0.42 netmask 255.0.0.0; Next come port d[...]

#vrrp_mode: block_crossconnect; The next sections determines t he failover mode between the Surviving Partner switches. Ther e are three modes: • switch - Failover by switch. Failover from Maste r switch to Backup on any port failure. The switch with the most links becomes the new Master. One port failure will cause the switch to failover. • vl[...]

Chapter 4 Fabric Switch Configu ration Two switches, two consoles There are two separate switch port ions in the Ethernet Switch Blade units, the base s witch and the fabric switch. The fabric switch handles the data traffic for the ATCA rack over ports 0-47. It runs the Ethernet Switch Blade softwar e. Two or four GigE connections are provided to [...]

Changing the Shell Prompt You may use standard bash shell procedures to change the prompts on your base switches. Many sites choose a system that distingui shes among the individual switches at their locati on. The same rules apply for saving your choice ( zsync) a s for all other configuration changes. Default Configuration Scripts As shipped the [...]

Overview of OpenArchitect VLAN In terfaces A zhp device is associated with one VLAN. zhp ma y have one or more physical ports and their associated zre devices. A VLAN from the viewpoint of the switch is a logical mapping of ports based on intended use. The primary purpose of a VLAN is to is olate traffic and enable communication to flow more effici[...]

Switch Port Interfaces For each switch port, OpenArchitect c reates a separate interface with its own MAC a ddress called a ZNYX raw Ethernet ( zre ). After the initial power up, 48 zre interfaces are created, one for each in band port. You cannot directly acce ss or modify the zre interfaces. During the initial power up of the switch, the de fault[...]

Layer 3 Switch Configuration The previous section outlines the Layer 2 switch configuration that is automatically confi gured when you initially bring up the OpenArchitec t switch. In order to communicate between Layer2 interfaces, you must properly setup routing. The steps to build a Layer 2 switch involve creating a group of switch ports in a VLA[...]

In the S50layer3 script separate VLANs are set up for ea ch port. The VLANs, are labeled as zhp0..zhpn . Each VLAN is associated with an individua l zre interface. There is always a one to one connection between VLANs and zhp interfac es. Remember, zre and zhp interfaces can begin with a zero value but a VLAN cannot (t hat is, zhp0 has zre0 on vlan[...]

Marking and Re-marking The OpenArchitect switch can mark or rem ark packets using the TOS field or 802.1p tag. This is also controlled through the Linux iptables utili ty. Scheduling The servicing of configured queues by the switc hing fabric is referred to as scheduling. The OpenArchitect switch has three built-i n scheduling algorithms. The type [...]

you may want to move your set of iptables commands t o a start up script to run upon initialization. This could be a ccomplished by creating a standalone " S " script and plac ing that script into / etc/rcZ.d . Restrictions on Implementation Several restrictions exist on the r ules that can be implemented on the FFP hardware. These includ[...]

On the other hand, in the following sequence of rule s, the position of the rule that drops SYN packets is important. Since the set of fi elds it examines is not a subset of the fields exa mined by the ACCEPT rules, and visa versa, the order ing rule given above does not apply. In this case, the order it is applied will be the same as it s position[...]

By default, INPUT, FORWARD and OUTPUT chains are insta lled on boot up. Additional rules can be installed for the other chains . Additionally, one can write software extensions to add mor e chains. Figure 4.2 provides an illustration of the Firewall Flow. When a packet reaches a circl e in the diagram, that chain is examined to decide the fate of t[...]

FORWARDING Chain supports all of them. tc and zqosd tc , which stands for Traffic Control, is a mec hanism for enabling Quality of Service on Linux. tc uses three functional objects: queuing dis ciplines , which comprise queuing and scheduling algorithms such as FIFO queues, priority queues, R ED queues, and token buckets; classes , which are leafs[...]

qdisc pfifo 100: dev zhp0 limit 32p The tc command is applied to a device, so dev zhp0 must be specified. Note that a VLAN, such as zhp0 , and a port, such as zre0 , are eac h treated as devices. Breakdown of the options: handle 100:0 Defines the handle for the queuing discipl ine. This handle may be used to reference the pfifo queue. Note that the[...]

The byte-limited FIFO queue case differs only s lightly from the packet-limited FIFO case. T he syntax is almost identical. In hardware the limit is based on 128-byte cells. The speci fied byte limit is divided by 128 to determine the cel l limit. Always specify a byte limit of at least 128 bytes to avoid setting the queue length to zer o. For exam[...]

So, thi s example would read: Priority 0 maps to Queue 1 Priority 1 maps to Queue 2 Priority 2 maps to Queue 2 Priority 3 maps to Queue 2 Priority 4 maps to Queue 3 Note that the tc priority map applies to a 4- bit field. With the Ethernet Switc h Blade, the[...]

The U32 Filter The U32 filter provides the capability to mat ch on fields in the L2, L3 or L4 header of a packet. Each match rule gives the locati on of the field to be tested, which is always a 32 bit word, a mas k selecting the bits to be test ed, and a value which is to be matched by the packet field. M any matches can be specified in one tc fi [...]

Marking and Re-marking The OpenArchitect switch can mark or rem ark packets using the TOS field or 802.1p tag. This is also controlled through the Linux iptables utili ty. Scheduling The servicing of configured queues by the switc hing fabric is referred to as scheduling. The OpenArchitect switch has three built-i n scheduling algorithms. The type [...]

Running zfilterd Before starting zfilterd , ztmd must be running. Your can star t both from within a script, or directly from the command line .

The order of the two rul es in the FORWARD chain does not matt[...]

Introduction Firewall rules are stored in tables. The se tables are sometimes also known as firewal l chains or just chains . Tables normally store rules for what are known as hooks , which can be looked as packet-path junctions. There are five de fined hooks: PRE-ROUTE, POST-ROUTE, INPUT, OUTPUT and FORWARDING. The example below illustrat es the d[...]

Packet Walk When a packet comes in via one of the int erface ports, the base switch makes a routi ng decision. If the packet was destined for the base switch itself or if the send to CPU action is speci fied, it is sent to the INPUT chain for further processing. If the re is no valid way to forward the packet, it is dropped. If the switch is config[...]

A range of ports can be specified by giving the first and last ports separate[...]
