Caution The BIOS on IPS 4260 is specific to IPS 4260 and must only be upgraded under instructions from Cisco with BIOS files obtained from the Cisco website. Installing a non-Cisco or third-party BIOS on IPS 4260 voids the warranty. For more information on how to obtain instructions and BIOS files from the Cisco website, see Obtaining Cisco IPS Software.

Introducing IPS 4260

IPS 4260 delivers 1 Gigabit of intrusion prevention performance. You can use IPS 4260 to protect both Gigabit subnets and aggregated traffic traversing switches from multiple subnets. IPS 4260 is a purpose-built device that has support for both copper and fiber NIC environments thus providing flexibility of deployment in any environment.

IPS 4260 has two built-in Gigabit Ethernet network ports and six expansion slots. The network port numbers increase from right to left and the expansion slot numbers increase from bottom to top and from right to left as shown in Figure 5-4. Slots 2 and 3 are PCI-Express connectors and the other expansion slots are PCI-X slots. Slots 1 through 3 are full-height slots and slots 4 though 6 are half-height slots. The built-in management port is called Management0/0 and the built-in sensing interface is Gigabit-Ethernet0/1.


Note Only expansion slots 2 and 3 are supported at this time.


For improved reliability, IPS 4260 uses a flash device for storage rather than a hard-disk drive. IPS 4260 supports two optional network interface cards, the 2SX Fiber card, and the 4GE bypass interface card that contains the hardware-bypass feature. Initially IPS 4260 supports only the built-in interfaces and these two interface cards.

IPS 4260 monitors greater than 1 Gbps of aggregate network traffic on multiple sensing interfaces and is also inline ready. It replaces IDS 4250-XL. It supports both copper and fiber interfaces.


Note The 1-Gbps performance for IPS 4260 is based on the following conditions: 10,000 new TCP connections per second, 100,000 HTTP transactions per second, average packet size of 450 bytes, and the system running IPS 6.0 software. The 1-Gbps performance is traffic combined from all sensing interfaces.


IPS 4260 ships with one power supply, but it supports redundant power supplies.


Note IPS 4260 operates in load-sharing mode when the optional redundant power supply is installed.



Note On IPS sensors with multiple processors (for example, the IPS 4260 and IPS 4270-20), packets may be captured out of order in the IP logs and by the packet command. Because the packets are not processed using a single processor, the packets can become out of sync when received from multiple processors.

Supported Interface Cards

IPS-4260supports two interface cards—the 4GE bypass interface card (part number IPS-4GE-BP-INT=) and the 2SX card (part number IPS-2SX-INT=).

GigabitEthernetslot_number/port_number is the expansion card interface naming convention for IPS 4260. The slot number is shown to the right of the slot in the chassis and the port number is numbered from right to left starting with 0.

4GE Bypass Interface Card

The 4GE bypass interface card provides four 10/100/1000BASE-T (4GE) monitoring interfaces (allowing up to 16 total monitoring interfaces). The 4GE bypass interface card supports hardware bypass.

Figure 5-1 shows the 4GE bypass interface card.

Figure 5-1 4GE Bypass Interface Card

2SX Card

The 2SX card provides two 1000BASE-SX (fiber) monitoring interfaces (allowing up to 12 total fiber monitoring interfaces). The 2SX card ports require a multi-mode fiber cable with an LC connector to connect to the SX interface of the sensor. The 2SX interface card does not support hardware bypass.

Figure 5-2 shows the 2SX interface card.

Figure 5-2 2SX Interface Card

Hardware Bypass

This section describes the 4GE bypass interface card and its configuration restrictions. It contains the following topics:

Hardware Bypass Link Status Changes and Drops

4GE Bypass Interface Card

IPS 4260 and IPS 4270-20 support the 4-port GigabitEthernet card (part number IPS-4GE-BP-INT=) with hardware bypass. This 4GE bypass interface card supports hardware bypass only between ports 0 and 1 and between ports 2 and 3.


Note To disable hardware bypass, pair the interfaces in any other combination, for example 2/0<->2/2 and 2/1<->2/3.


Hardware bypass complements the existing software bypass feature in IPS 6.0. The following conditions apply to hardware bypass and software bypass:

When bypass is set to OFF, software bypass is not active.

For each inline interface for which hardware bypass is available, the component interfaces are set to disable the fail-open capability. If SensorApp fails, the sensor is powered off, reset, or if the NIC interface drivers fail or are unloaded, the paired interfaces enter the fail-closed state (no traffic flows through inline interface or inline VLAN subinterfaces).

When bypass is set to ON, software bypass is active.

Software bypass forwards packets between the paired physical interfaces in each inline interface and between the paired VLANs in each inline VLAN subinterface. For each inline interface on which hardware bypass is available, the component interfaces are set to standby mode. If the sensor is powered off, reset, or if the NIC interfaces fail or are unloaded, those paired interfaces enter fail-open state in hardware (traffic flows unimpeded through inline interface). Any other inline interfaces enter fail-closed state.

When bypass is set to AUTO (traffic flows without inspection), software bypass is activated if sensorApp fails.

For each inline interface on which hardware bypass is available, the component interfaces are set to standby mode. If the sensor is powered off, reset, or if the NIC interfaces fail or are unloaded, those paired interfaces enter fail-open state in hardware. Any other inline interfaces enter the fail-closed state.


Note To test fail-over, set the bypass mode to ON or AUTO, create one or more inline interfaces and power down the sensor and verify that traffic still flows through the inline path.


For More Information

For the procedure for installing and removing the 4GE bypass interface card, see Installing and Removing Interface Cards.

For more information on software bypass mode, refer to Configuring Bypass Mode.

Hardware Bypass Configuration Restrictions

To use the hardware bypass feature on the 4GE bypass interface card, you must pair interfaces to support the hardware design of the card. If you create an inline interface that pairs a hardware-bypass-capable interface with an interface that violates one or more of the hardware-bypass configuration restrictions, hardware bypass is deactivated on the inline interface and you receive a warning message similar to the following:

Hardware bypass functionality is not available on Inline-interface pair0. 
Physical-interface GigabitEthernet2/0 is capable of performing hardware bypass only when 
paired with GigabitEthernet2/1, and both interfaces are enabled and configured with the 
same speed and duplex settings.
 
   

The following configuration restrictions apply to hardware bypass:

The 4-port bypass card is only supported on IPS 4260 and IPS 4270-20.

Fail-open hardware bypass only works on inline interfaces (interface pairs), not on inline VLAN pairs.

Fail-open hardware bypass is available on an inline interface if all of the following conditions are met:

Both of the physical interfaces support hardware bypass.

Both of the physical interfaces are on the same interface card.

The two physical interfaces are associated in hardware as a bypass pair.

The speed and duplex settings are identical on the physical interfaces.

Both of the interfaces are administratively enabled.

Autonegotiation must be set on MDI/X switch ports connected to IPS 4260 and IPS 4270-20.

You must configure both the sensor ports and the switch ports for autonegotiation for hardware bypass to work. The switch ports must support MDI/X, which automatically reverses the transmit and receive lines if necessary to correct any cabling problems. The sensor is only guaranteed to operate correctly with the switch if both of them are configured for identical speed and duplex, which means that the sensor must be set for autonegotiation too.

Hardware Bypass Link Status Changes and Drops

Properly configuring and deploying hardware bypass protects against complete link failure if the IPS appliance experiences a power loss, critical hardware failure, or is rebooted; however, a link status change still occurs when hardware bypass engages (and again when it disengages).

During engagement, the interface card disconnects both physical connections from itself and bridges them together. The interfaces of the connected devices can then negotiate the link and traffic forwarding can resume. Once the appliance is back online, hardware bypass disengages and the interface card interrupts the bypass and reconnects the links back to itself. The interface card then negotiates both links and traffic resumes.

There is no built-in way to completely avoid link status changes and drops. However, you can greatly reduce the interruption time (in some cases to sub-second times) by doing the following:

Make sure you use CAT 5e/6-certified cabling for all connections.

Make sure the interfaces of the connected devices are configured to match the interfaces of the appliance for speed/duplex negotiation (auto/auto).

Enable portfast on connected switchports to reduce spanning-tree forwarding delays.
