Overview of Cisco RF Gateway 10 UEQAM Platform
The Cisco RFGW-10 is a carrier-class Universal Edge QAM (UEQAM) platform that offers concurrent support for standard and high-definition digital broadcast television, Switched Digital Video (SDV), Video on Demand (VoD), and DOCSIS/Modular CMTS services. It is a chassis-based product based on open standards with superior performance, capacity, power consumption, ease of management, and scalability. All components of the Cisco RFGW-10 are designed for high availability, including dual supervisor and Ethernet switching line cards, 1:N Universal Edge QAM line cards, dual timing, communication and control (TCC) line cards, dual load balancing and load sharing DC PEMs and integrated RF switching modules.
The Cisco RFGW-10 is targeted to cable operators worldwide, and is optimized for operators requiring carrier-class high availability solutions and wanting to collapse video and data over cable EQAM systems into a common platform. A collapsed Universal EQAM architecture achieves the following business benefits: EQAM resource utilization gains, cost efficiencies, rack space optimization, reduced cost and complexity of management, and high availability for all services. The Cisco RFGW-10 is part of the Cisco cable ecosystem, and is fully integrated and tested as part of the Cisco Digital Broadband Delivery System (DBDS) video solution and the Cisco uBR10012 DOCSIS 3.0 and Modular CMTS solution.
The Cisco RFGW-10 is a centralized switching architecture leveraged from the Cisco Catalyst 4500 Series switches. The Cisco RFGW-10 is a 13-rack unit, modular chassis designed for providing front-to-back airflow and system-level redundancy. All chassis components are hot-swappable and redundant. The chassis supports "wire-once" cabling for RF line cards and an integrated dual-zone RF switch matrix. The Supervisor engine provides non-blocking, robust Layer 2 to Layer 4 switching with the addition of wire-speed 10-Gigabit Ethernet uplinks, 136 Gbps capacity, and 102 mpps packet throughput.
The Cisco RFGW-10 system is a UEQAM platform that supports both upstream and downstream RF line cards over a frequency range of 5 MHz to 1.2 GHz. The initial line card release is a UEQAM downstream card that supports the DOCSIS (1.0/2.0/3.0), the EURODOCIS, and J-DOCSIS specifications. Additionally, the RF line card supports high definition digital broadcast television, Switched Digital Video (SDV), and Video on Demand (VoD) video delivery.
Based on the Cisco IOS networking software, the Cisco RFGW-10 supports advanced switching and routing features. The platform supports full upgradeability, ensuring investment protection as software enhancements and industry standards continue to evolve.
System Requirements

•
Hardware Supported
Table 1 provides information on the hardware supported on the Cisco RFGW-10.
Software Compatibility
Cisco IOS Release 12.2(44)SQ is the first deployment release of the Cisco RFGW-10. It is based on Cisco IOS Release 12.2(44)SG1 for the Cisco Catalyst 4500 platform. The Cisco RFGW-10 and Catalyst 4500 share common Cisco IOS software on the Supervisor card. Therefore, there is IOS feature parity in Cisco IOS Release 12.2(44)SQ with release 12.2(44)SG1. The Cisco RFGW-10 features are supported only on Cisco IOS Release 12.2(44)SQ.
Cisco IOS Release 12.2(50)SQ is based on Cisco IOS Release 12.2(50)SG4 for the Cisco Catalyst 4500 platform. Therefore, Cisco IOS Release 12.2(50)SQ has IOS feature parity with Cisco IOS Releas 12.2(50)SG4. The Cisco IOS Release 12.2(50)SQ provides Cisco RFGW-10 specific features as described.

Cisco RFGW DS48 Universal EQAM Line Card
The Cisco RFGW-10 DS48 line card is a 12-port, 48-channel UEQAM card designed to support Downstream External PHY Interface DOCSIS MPEG Transport (DEPI D-MPT), downstream data traffic, and video applications (VoD, SDV, and broadcast video). The DS48 card is similar to the traditional QAM solutions where the card receives encapsulated data, depacketizes and reformats the packets, maps them to the output QAM channel, and performs QAM modulation and frequency upconversion. From a high level, the DS48 line card receives video and DOCSIS data encapsulated over Ethernet and outputs analog QAM data to the subscriber devices (set top box (STB) and DOCSIS modems).
As a DOCSIS engine, the DS48 line card supports DEPI D-MPT mode. DEPI is based on the L2TPv3 protocol, which includes a data plane and a control plane. DEPI data plane traffic is terminated at the line card. The Cisco RFGW-10 Supervisor card terminates DEPI control and communicates the control to each line card in the system via the chassis IPC infrastructure. DOCSIS timing information (10.24 MHz synchronous DTI clock) is received by the line card from the system TCC cards.
As a video engine, the DS48 terminates video data path traffic forwarded from the Supervisor card (video control plane traffic is terminated and processed by the system Supervisor card). The DS48 processing path classifies video packets, performs inter-QAM processing, bitrate scheduling, program muxing and scheduling, program identifier (PID) remapping, program clock references (PCR) restamping, and CC restamping.
The DS48 line card has 12 physical RF ports, which support up to four QAMs per port. The number of QAM outputs is configurable on a per-port basis (meaning an individual port can support 1, 2, or 4 QAMs as well as muting of individual QAMs within a QAM group). In stacked QAM mode, the QAMs are stacked contiguously over a 24-MHz or 32-MHz band. The line card supports a downstream channel frequency range of 88 MHz to 870 MHz.
Table 3 provides the DOCSIS and EuroDOCSIS downstream rates:
The front panel display includes two Gigabit Ethernet ports and a single DVB-ASI interface (covers all video output streams). The front panel connectors support both copper and fiber SFP modules. The front panel Gigabit Ethernet ports are not processed directly by the line card; these are independent of the line card and route directly to the Supervisor card switch fabric. These ports do not go out of service if the line card crashes and a failover to the redundant card occurs.
A critical feature of the DS48 line card is redundancy and high availability support. The line cards are designed to detect and react to a wide range of faults and failures, and respond with sub-second failover to a dedicated protect card. In the Cisco RFGW-10 platform, DS48 line cards can be configured with 1:N redundancy (up to 1:9), resulting in a fully-protected, high capacity, and highly dense EQAM solution.

Cisco RF Gateway 10 Supervisor Engine V-10GE
The Cisco RFGW-10 Supervisor Engine V-10GE provides data path and data control for all network interfaces and provides 10-Gigabit Ethernet interfaces for uplink connections. The Cisco RFGW-10 supervisor design is leveraged from the Cisco Catalyst 4500 Series switch supervisor family.
The Supervisor Engine V-10GE has a very high performance Ethernet switching feature set. Advanced traffic management features include:
•
•
•
•
The Cisco RFGW-10 Supervisor Engine V-10GE handles the management of DOCSIS and video traffic for the RF Gateway 10 system. Management of data and video traffic can be split into data plane and control plane processing. The data plane manages the aggregation and forwarding of multiple services to the edge QAM resources (for example, Ethernet switching, routing, aggregation, and filtering). Interactions with control interfaces for video and Data over Cable Service Interface Specifications (DOCSIS) are managed by the control plane (for example, setup and tear-down of video sessions, creation of VoIP calls, management of high-speed data services, and management of the distribution of packets and environmental factors in the gateway). The aggregation management utility in the supervisor engine allows cable operators to extract detailed information from a single line card on the overall operational status of the entire gateway.
The supervisor engine receives either DEPI (DOCSIS) data or video data (MPEG/UDP/IP) and forwards the data to the RF line cards based on either the DEPI session content (IP/L2TP) or encapsulated video session information (IP/UDP). All data path traffic is terminated at the line cards. The supervisor engine receives data traffic, classifies the traffic, and forwards the data traffic to the line cards.
Control traffic for DOCSIS (DEPI mode), video, and HA functionality is terminated on the supervisor engine. Local video mode (CLI, GUI, SNMP), remote video mode control plane (DNCS, GQI), and native video mode (GQI v2, object model) are implemented in the IOS and terminated at the supervisor engine.
The following defines the LEDs, connectors, and switches on the Cisco RFGW-10 Supervisor Engine V-10GE:

RFGW-10 RF Switch Cards
The RF Switch provides RF data path redundancy at both the line card (slot) level and the RF port level for bidirectional DOCSIS traffic up to 1.2 GHz. Additionally, the RF Switch cards are the coaxial cable termination point for the Cisco RFGW-10.
Functionally the RFGW-10-RFSW1 card physically switches out a failed line card (port by port) at the RF data path level. The card is capable of supporting two simultaneous RF line card failures. It is designed to support dual 1:N redundancy groups (where N is a group of RF line cards associated with a single protect card).
There are 12 RF Switch cards per chassis, providing 120 RF ports for the system.
Note
Each RF Switch card supports a single Cisco UCH2 connector header; the UCH2 supports 10 MCX coaxial connections per card. The RF Switch card is physically separate from the RF line card slots allowing insertion or removal of the RF line cards without disruption of the cable plant wiring.
The RF Switch card is the central hardware component for chassis-level HA features. The card can be configured and controlled via the system-level CLI functionality. The RF Switch card is a hardware and firmware-based module (no operating software) that can be field-upgraded via the chassis command line interface (CLI).
The RF Switch card faceplate includes a single LED. The LED does not indicate a line card failover.
RFGW-10 TCC Cards
The Cisco RFGW-10 UEQAM supports two Timing, Communication, and Control (TCC) slots. The TCC card acts as a secondary processor that controls the overall system clock generation and distribution, DOCSIS time-stamp synchronization, and system control of the front panel display (FPD), and the RF Switch cards.
The most critical function of the TCC card is distribution of the system clocking, in particular the DOCSIS Timing Interface (DTI). The TCC card is a DTI client interface. It supports dual DTI external input allowing DTI server redundancy. Based on the DTI input information, the TCC card generates DOCSIS 10.24-MHz clock and time-stamp information to every line card in the chassis. All clocks and DOCSIS information are redundant. When there is no external DTI clock, the TCC card provides an internal DOCSIS DTI clock and time-stamp reference.
When two TCC cards are installed, they are configured as active and backup (redundant). If the TCC card in the first slot is working at system power-up, it automatically becomes the active card and the TCC card in the second slot becomes the backup card (typically slot 13 boots as the primary TCC card and slot 14 as the secondary, but this is not mandatory).
In terms of the overall system high availability, the TCC cards work autonomously from the centralized control mechanisms. Redundant TCC cards monitor each other's priority information so that when the active card fails, the active card role is transferred to the redundant backup card without loss of data.
The following is a summary of the TCC card's functions and features:
•

RFGW-10-PWR-DC1 (DC PEM)
The Cisco RFGW-10 system is powered by redundant DC PEMs. An individual PEM is capable of providing 4536 watts of total output. Redundant modules work as a 1:1 redundancy configuration supporting current sharing and online insertion and removal (OIR) (hot swapping).
Each PEM includes two 60A input lines that operate between -40 VDC and -72 VDC input voltages. Proper configuration and operation requires that both DC inputs are properly wired. The PEM also includes an earth ground connection (this is not power return) for grounding the chassis.
DC PEM features:

RFGW-10 Fan Assembly
The Cisco RFGW-10 UEQAM system uses a modular fan assembly to dissipate heat from the system and control the temperature of the chassis system components (except the DC PEM, which contains its own internal fan). The fan assembly is a multi-fan design that pulls ambient air from the lower front of the chassis and exhausts air out of the rear top of the chassis. The fan assembly provides individual fan control and failure monitoring, multiple thermistors to monitor exhaust air and a wide range of speed control parameters based on the system and the environmental conditions. Inlet air monitoring is communicated to the fan tray via the system software from the sensors on each of the RF line cards.
The fan tray module provides the following features:

New Software Features in Cisco IOS Release 12.2(50)SQ
This section describes the new and modified software features supported in Cisco IOS Release 12.2(50)SQ.
Supervisor Stateful Switchover
In the Supervisor Stateful Switchover (SSO) mode, the standby Supervisor card is fully initialized and configured. This allows SSO to reduce the switchover time if the active Supervisor card fails, or if a manual switchover is performed. Both the startup and running configurations are continually synchronized from the active to the standby Supervisor cards, and the line cards are not reset during a Supervisor switchover. The interfaces remain active during the switchover, hence the neighboring routers do not detect a physical link flap (the link does not go down and back up).
The SSO feature supports both the DEPI Manual and the DEPI Protocol modes. It is unavailable for Video in Cisco IOS Release12.2(50)SQ.
For more information, see 1:1 Supervisor Card Redundancy.
M-CMTS DEPI Control Plane
The Downstream External PHY Interface (DEPI) control plane is based upon Layer Two Tunneling Protocol-Version 3 (L2TPv3) signaling. The DEPI is the communication protocol over an IP tunnel between the Modular Cable Modem Termination Systems (M-CMTS) core and the Edge Quadrature Amplitude Modulation (EQAM). It is an IP tunnel between the MAC (M-CMTS Core) and PHY (EQAM) in an M-CMTS system, which contains both a data path for Data-Over-Cable Service Interface Specifications (DOCSIS) frames and a control path for setting up, maintaining, and tearing down data sessions.
The DEPI Latency Measurement (DLM) packet is a special type of data packet used for measuring the network latency between the M-CMTS core and the EQAM.
For more information, see M-CMTS DEPI Control Plane.
Video Control Plane with Generic QAM Interface (GQI)
The Generic QAM Interface (GQI) based video control plane provides video session management through a GQI signaling protocol with Digital Network Control System (DNCS) and Universal Session/Resource Manager (USRM).
The GQI supports the following:
•
•
•
•
For more information, see Video.
1:1 and 1:N DS48 Line Card Redundancy for Video and DEPI
The line card redundancy (LCRED) feature introduced in Cisco IOS Release 12.2(44)SQ supports DEPI D-MPT traffic under the DEPI Manual mode. In Cisco IOS Release 12.2(55)SQ, line card redundancy supports Video and DEPI D-MPT with DEPI Control Plane in the DEPI Protocol mode. In case of line card failure, OIR, or a forced line card switchover, the standby line card becomes active and continues to process Video or DEPI traffic.
For more information, see the 1:1 and 1:N DS-48 Line Card Redundancy.
New Software Features in Cisco IOS Release 12.2(44)SQ2
This section describes the new and modified software features supported in Cisco IOS Release 12.2(44)SQ2.
Bundled Image upgrade enhancements
The Supervisor image is bundled with upgrades for all device images. The Supervisor card automatically checks the versions of the software and firmware on all line cards during system boot up and upgrades as necessary.
For more information, see Bundled Image Upgrade.
New Software Features in Cisco IOS Release 12.2(44)SQ1
There are no new software features supported in Cisco IOS Release 12.2(44)SQ1.
New Software Features in Cisco IOS Release 12.2(44)SQ
Below are the software features supported on the Cisco RFGW-10 for Cisco IOS Release 12.2(44)SQ.
Universal Edge Quadrature Amplitude Modulation
The Universal EQAM platform integrates the capabilities of an M-CMTS EQAM platform and the capabilities of a video EQAM, thereby supporting both DOCSIS and digital video services in a single UEQAM platform. The granularity of the DOCSIS and video traffic mix is per 4-channel group, that is, per RF port.
The Universal EQAM can be configured with 64 QAM or 256 QAM Downstream Modulation with 1:4 Frequency Stacking under Annex B, Annex A, or Annex C.
M-CMTS DOCSIS MPEG Transport Manual Mode
The interface between the M-CMTS core and the EQAM is defined by Downstream External PHY Interfaces (DEPI), which is an L2TP-based IP tunnel containing both a data path for DOCSIS frames and a control path for session setup, maintenance, and tear-down. This feature supports the DEPI data path with the DOCSIS MPEG Transport (D-MPT) mode with manual configuration for session setup.
D-MPT places integer number of MPEG transport packets into the L2TP payload. Only one D-MPT flow can be present in a QAM channel. The EQAM extracts the D-MPT packets within the DEPI payload and forwards them to the output QAM.
The D-MPT feature supports bonded DOCSIS through downstream channel bonding. Channel bonding is a technique of grouping multiple QAM channels into a bonding group to provide a logical downstream channel with larger aggregated bandwidth. Bonded traffic can be encapsulated in D-MPT.
D-MPT traffic from the M-CMTS core contains SYNC messages (DOCSIS time stamps). The EQAM finds all the SYNC messages in the D-MPT payload and performs the SYNC correction.
DTI Offset
The DOCSIS Timing Interface (DTI) Offset feature enables DOCSIS timing offset adjustment per channel in the RFGW-10 DS48 line card. The operator must measure the actual timing offset adjustment required on each QAM channel first and then use the DTI Offset CLI to make the adjustment. To configure all the QAM ports to the same timing offset, use the cable depi offset command specifying the port range of the QAM interfaces. With this command, users can configure an entire chassis with the same timing offset.
1:1 and 1:N DS48 Line Card Redundancy
The RFGW-10 supports both 1:1 and 1:N line card redundancy schemes. 1:1 redundancy refers to a configuration where a line card has a dedicated backup card. 1:N redundancy means one line card protecting N line cards. Therefore, a single DS48 line card can protect as many as nine other line cards. There can be up to two line card redundancy groups in an RFGW-10 chassis with each group being 1:1 or 1:N redundancy.
The RFGW-10 performs line card switchover on such events as a user-initiated switchover command, line card insertion and removal (OIR), as well as hardware and software faults, RF upconverter failure, and DTI failure on the line card. At line card switchover, the standby line card becomes active, resuming the functions of the line card it is switched from. With the internal RF Switch card, line card switchover is transparent to the RF connections to the plant.
The line card redundancy supports M-CMTS D-MPT traffic. The line card switchover has little impact on the DOCSIS applications. This release does not provide line card redundancy support for video applications.
1:1 Supervisor Card Redundancy
The Cisco IOS Route Processor Redundancy (RPR) feature enables the RFGW-10 to use two Supervisor cards in a redundant configuration, such that if the active Supervisor card fails or becomes inactive, the system automatically performs a switchover, where the standby Supervisor card takes over and assumes full responsibility for systems operations.
The RPR mode is the simplest mode in which the standby Supervisor card completes its initialization but suspends just before parsing the startup-config. The standby monitors the active Supervisor and switches over when it detects a failure on the active Supervisor or when the user issues a switchover command. When the standby Supervisor card becomes active, all the line cards in the chassis are reset and the startup-config is parsed. There will be a traffic outage in this mode because the line cards are reset.
1:1 Timing, Communication and Control (TCC) Card Redundancy
The Timing, Communication and Control (TCC) card operates in 1:1 redundancy configuration in the RFGW-10 chassis, where each TCC card has its own peer as a dedicated backup card in case of failure (hot standby mode). Only one of the two TCC cards provides the DTI client functionality at any given time. The standby TCC is accessible from other line cards, but does not provide any DTI functionality. In the event of active TCC failure, the standby TCC becomes active and serves as the DTI client.
Video
The Cisco RFGW-10 performs MPEG-2 video processing for Video on Demand (VoD) and Digital Video Broadcast applications. The video feature involves both video control plane and video data plane functions. The control plane resides on the Supervisor card and the data plane runs on the DS48 line card.
The video control plane provides video session configurations with table-based UDP port-to-QAM port mapping. The table-based mapping is used only for unicast video sessions. Apart from the table-based mapping, the Cisco RFGW-10 also supports the flexible port mapping method, where the users can set up video sessions by configuring the mapping dynamically. The flexible port mapping can be used for both unicast and multicast video sessions. In addition, the video control plane provides show commands for users to access run-time session information.
The video data plane processes Unicast Constant Bit Rate (CBR) Single Program Transport Stream (SPTS) for VoD sessions with Trick Mode support, which provides functionalities like fast forward, rewind, and pause for an MPEG stream. It also serves Multicast Multiple Program Transport Stream (MPTS) for DVB Pass-Through sessions.
The data plane supports the video feature with a number of video-processing functions including Program ID (PID) remapping, Program Clock Reference (PCR) restamping, Dejittering and Clock Recovery, and Program Specific Information (PSI) processing.
SNMP MIBs
The Cisco RFGW-10 provides network management with a set of standard-based MIBs. The MIBs specific to the Cisco RFGW-10 platform include:
•
•
•
•
•
•
•
•
In addition, the Cisco RFGW-10 supports MIBs common in Cisco IOS which can be found in the Cisco RF Gateway 10 MIB Specifications Guide.
GUI Monitoring
GUI Monitoring is a web-based tool that enables operators to monitor the RFGW-10 system. GUI Monitoring is comprised of two functional components: a web browser client on a computer and a Web server residing in the Cisco RFGW-10 Supervisor card. The web browser accesses the Cisco RFGW-10 via an authenticated IP connection to the RFGW-10.
The GUI includes the following monitoring pages:

Important Notes
Cisco IOS Behavior Changes
Behavior changes describe the minor modifications to the way a device works that are sometimes introduced in a new software release. These changes typically occur during the course of resolving a software defect and are therefore not significant enough to warrant the creation of a stand-alone document. When behavior changes are introduced, existing documentation is updated with the changes described in this section.
Cisco IOS Release 12.2(44)SQ2
This section describes the behavior changes introduced on the Cisco RFGW-10 platform in Cisco IOS Release 12.2(44)SQ2.
•
Old Behavior: The cable image-upgrade download command upgrades all the images on the line card. The background keyword is used so that the upgrade occurs in the background and the control is returned to the command prompt.
New Behavior: Using the forced option in the cable image-upgrade download command forces the upgrade on all the devices on the line card.
Additional information: For more information, see the Cisco RF Gateway 10 Command Reference.
Cisco IOS Release 12.2(44)SQ1
This section describes the behavior changes introduced on the Cisco RFGW-10 platform in Cisco IOS Release 12.2(44)SQ1.
•
Old Behavior: The show cable line card version command displays the image version information of the line card. The application upgrade version, Rommon version, and image version are displayed.
New Behavior: The show cable line card version command displays the application permanent version in addition to the application upgrade version, Rommon version, and image version fields.
Additional information: For more information, see the Cisco RF Gateway 10 Command Reference.

CSCsk64158
Symptoms: Several features within Cisco IOS software are affected by a crafted UDP packet vulnerability. If any of the affected features are enabled, a successful attack will result in a blocked input queue on the inbound interface. Only crafted UDP packets destined for the device could result in the interface being blocked, transit traffic will not block the interface.
Cisco has released free software updates that address this vulnerability.
Workarounds that mitigate this vulnerability are available in the workarounds section of the advisory. This advisory is posted at the following link: http://www.cisco.com/warp/public/707/cisco-sa-20090325-udp.shtml.
CSCso04657
Symptoms: SSLVPN service stops accepting any new SSLVPN connections.
Conditions: A device configured for SSLVPN may stop accepting any new SSLVPN connections, due to a vulnerability in the processing of new TCP connections for SSLVPN services. If "debug ip tcp transactions" is enabled and this vulnerability is triggered, debug messages with connection queue limit reached will be observed. This vulnerability is documented in two separate Cisco bug IDs, both of which are required for a full fix: CSCso04657 and CSCsg00102.
CSCsv04836
Multiple Cisco products are affected by denial of service (DoS) vulnerabilities that manipulate the state of Transmission Control Protocol (TCP) connections. By manipulating the state of a TCP connection, an attacker could force the TCP connection to remain in a long-lived state, possibly indefinitely. If enough TCP connections are forced into a long-lived or indefinite state, resources on a system under attack may be consumed, preventing new TCP connections from being accepted. In some cases, a system reboot may be necessary to recover normal system operation. To exploit these vulnerabilities, an attacker must be able to complete a TCP three-way handshake with a vulnerable system.
In addition to these vulnerabilities, Cisco Nexus 5000 devices contain a TCP DoS vulnerability that may result in a system crash. This additional vulnerability was found as a result of testing the TCP state manipulation vulnerabilities.
Cisco has released free software updates for download from the Cisco website that address these vulnerabilities. Workarounds that mitigate these vulnerabilities are available.

CSCsw23043
Symptom: Resetting one line card causes a momentary glitch on another line card.
Condition: This issue occurs only when the hw-module slot reset command is issued.
Workaround: Use the cable linecard reset command to reset a line card.
CSCsw26480
Symptom: When un-muting an RF port, the RF power level tends to raise the noise floor around the RF channels supported momentarily (for several hundreds of milliseconds). There are no reported issues of cable modem performance, though impact is observable on a spectrum analyzer.
Condition: This issue occurs during muting the RF port output power.
Workaround: There is no workaround.
CSCsw26789
Symptom: The DocsDevEvent table does not function.
Condition: When the MIB table is accessed, there is no data returned.
Workaround: There is no workaround.
CSCsx24891
Symptom: The SNMP trap message is not displayed in the log file for line card reset.
Condition: The SNMP trap works when running shut/no shut interface command on the line card, but, the trap message is not logged after a line card reset.
Workaround: Use snmp-server queue-length command to increase the size of the trap queue.
During line card reset, some trap messages could be dropped because of trap queue overflow on the device. If trap messages are being dropped, the size of the trap queue may be increased (for example, to 1000) to determine if trap messages can be sent during line card reset.
For the detail of snmp-server queue-length, please see http://www.cisco.com/en/US/docs/ios/netmgmt/command/reference/nm_20.html#wp1012887

CSCsm27071
A vulnerability in the handling of IP sockets can cause devices to be vulnerable to a denial of service attack when any of several features of Cisco IOS software are enabled. A sequence of specially crafted TCP/IP packets could cause any of the following results:
The configured feature may stop accepting new connections or sessions.
The memory of the device may be consumed.
The device may experience prolonged high CPU utilization.
The device may reload. Cisco has released free software updates that address this vulnerability.
Workarounds that mitigate this vulnerability are available in the "workarounds" section of the advisory. The advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-ip.shtml
