Command History

Release	Modification
12.2(4)B	This command was introduced.
12.2(13)T	This command was integrated into Cisco IOS Release 12.2(13)T.

Usage Guidelines

Use the server command in SSG-redirect-group configuration mode to add a server, defined by its IP address and TCP port, to a captive portal group.

Service Selection Gateway (SSG) TCP Redirect for Services provides nonauthorized users access to controlled services within an SSG. Packets sent upstream from an unauthenticated user are forwarded to the captive portal that deals with the packets in a suitable manner, such as routing them to a logon page. You can also use captive portals to handle requests from authorized users who request access to services into which they are not logged.

You must enable SSG using the ssg enable command and SSG TCP Redirect for Services using the ssg tcp-redirect command before you can define a captive portal group. Use the server-group command in SSG-redirect configuration mode to create and name a captive portal group before using the server command to add servers to the captive portal group.

Examples

The following example adds a server at IP address 10.0.0.0 and TCP port 8080 and a server at IP address 10.1.2.3 and TCP port 8081 to a captive portal group named "RedirectServer":

ssg enable

 ssg tcp-redirect

  server-group RedirectServer

   server 10.0.0.0 8080

   server 10.1.2.3 8081

Command Modes

BBA group configuration

Command History

Release	Modification
12.2(15)T	This command was introduced.

Usage Guidelines

Continuous repeated requests to initiate PPPoE sessions can seriously affect the performance of a router and RADIUS server. Use the sessions throttle command to configure the PPPoE server to limit the number of requests for PPPoE sessions that can be made from a MAC address or VC during a configured period of time.

If a client exceeds the configured number of allowable session requests (session-requests) within the configured time limit (session-request-period), the PPPoE server accepts only the allowable number of session requests and blocks the MAC address or VC from making any more requests for a configured period of time (blocking-period).

After the blocking-period expires, the PPPoE server will again accept the configured number of session requests from the MAC address or VC within the configured session-request-period.

Examples

The following example shows the configuration of per-VC and per-MAC PPPoE connection throttling in PPPoE profile "grp1":

bba-group pppoe grp1

shape fr-voice-adapt [deactivation seconds]

no shape fr-voice-adapt

Syntax Description

deactivation seconds

(Optional) Number of seconds that must elapse after the last voice packet is transmitted before the sending rate is increased to the committed information rate (CIR). The range is from 1 to 10000.

Defaults

Frame Relay voice-adaptive traffic shaping is not enabled.
Seconds: 30

12.2(15)T	This command was introduced.

Usage Guidelines

Frame Relay voice-adaptive traffic shaping enables a router to reduce the permanent virtual circuit (PVC) sending rate to the minimum CIR (minCIR) whenever packets (usually voice) are detected in the low latency queueing priority queue or H.323 call setup signaling packets are present. When there are no packets in priority queue and signaling packets are not present for a configured period of time, the router increases the PVC sending rate from minCIR to CIR to maximize throughput.

The shape fr-voice-adapt command can be configured only in the class-default class. If you configure the shape fr-voice-adapt command in another class, the associated Frame Relay map class will be rejected when you attach it to the interface.

Frame Relay voice-adaptive traffic shaping can be used with other types of adaptive traffic shaping. For example, when both voice-adaptive traffic shaping and adaptive shaping based on interface congestion are configured, the sending rate will change to minCIR if there are packets in the priority queue or the interface queue size exceeds the configured threshold.

---

Note Although the priority queue is generally used for voice traffic, Frame Relay voice-adaptive traffic shaping will respond to any packets (voice or data) in the priority queue.

---

In order to use Frame Relay voice-adaptive traffic shaping, you must have low latency queueing and traffic shaping configured using the Modular QoS CLI.

Examples

The following example shows the configuration of Frame Relay voice-adaptive traffic shaping and fragmentation. With this configuration, priority- queue packets or H.323 call setup signaling packets destined for PVC 100 will result in the reduction of the sending rate from CIR to minCIR and the activation of FRF.12 end-to-end fragmentation. If signaling packets and priority-queue packets are not detected for 50 seconds, the sending rate will increase to CIR and fragmentation will be turned off.

VCD/Name	Virtual circuit descriptor (virtual circuit number). The connection name is displayed if the virtual circuit (VC) was configured using the pvc command and the name was specified.
VPI	Virtual path identifier.
VCI	Virtual channel identifier.
Type	Type of VC, either PVC, SVC, TVC, or multipoint SVC (MSVC). •MSVC (with no -x) indicates that VCD is a leaf of some other router's multipoint VC. •MSVC-x indicates there are x leaf routers for that multipoint VC opened by the root. Type of PVC detected from PVC discovery, either PVC-D, PVC-L, or PVC-M. •PVC-D indicates a PVC created due to PVC discovery. •PVC-L indicates that the corresponding peer of this PVC could not be found on the switch. •PVC-M indicates that some or all of the Quality of Service (QoS) parameters of this PVC do not match those of the corresponding peer on the switch. •TVC indicates a Tag VC.
Encaps	Type of ATM adaptation layer (AAL) and encapsulation.
PeakRate	Kilobits per second sent at the peak rate.
Average Rate	Kilobits per second sent at the average rate.
Burst Cells	Value that equals the maximum number of ATM cells the VC can send at peak rate.
Status	Status of the VC connection. •UP indicates that the connection is enabled for data traffic. •DOWN indicates that the connection is not ready for data traffic. When the Status field is DOWN, a State field is shown. •INACTIVE indicates that the interface is down. •ACTIVE indicates that the interface is in use and active.
etype	Encapsulation type.
Flags	Bit mask describing VC information. The flag values are summed to result in the displayed value. 0x10000 ABR VC 0x20000 CES VC 0x40000 TVC 0x100 TEMP (automatically created) 0x200 MULTIPOINT 0x400 DEFAULT_RATE 0x800 DEFAULT_BURST 0x10 ACTIVE 0x20 PVC 0x40 SVC 0x0 AAL5-SNAP 0x1 AAL5-NLPID 0x2 AAL5-FRNLPID 0x3 AAL5-MUX 0x4 AAL3/4-SMDS 0x5 QSAAL 0x6 AAL5-ILMI 0x7 AAL5-LANE 0x8 AAL5-XTAGATM 0x9 CES-AAL1 0xA F4-OAM
VCmode	AIP-specific or NPM-specific register describing the usage of the VC. This register contains values such as rate queue, peak rate, and AAL mode, which are also displayed in other fields.
OAM frequency	Seconds between OAM loopback messages, or DISABLED if OAM is not in use on this VC.
InARP frequency	Minutes between Inverse Address Resolution Protocol (InARP) messages, or DISABLED if InARP is not in use on this VC.
virtual-access	Virtual access interface identifier.
virtual-template	Virtual template identifier.

InPktDrops	A non-zero value for the InPktDrops of a VC counter suggests that the ATM interface is running out of packet buffers for an individual VC, or is exceeding the total number of VC buffers that can be shared by the VCs.
OutPktDrops	The PA-A3 driver increments the OutPktDrops counter when a VC fills its individual transmit buffer quota. The purpose of the quota is to prevent a consistently over-subscribed VC from grabbing all of the packet buffer resources and hindering other VCs from transmitting normal traffic within their traffic contracts.
InCellDrops	Number of incoming cells dropped on this VC.
OutCellDrops	Number of outgoing cells dropped on this VC.
InByteDrops	Number of incoming bytes that are dropped on this VC.
OutByteDrops	Number of outgoing bytes that are dropped on this VC.

LengthViolation	Number of length violations on this VC. A length violation occurs when a reassembled packet is dropped without checking the CRC.
CPIErrors	The Common Part Indicator error field is a one octet field in the AAL5 encapsulation of an ATM cell and must be set to 0. If it is received with some other value, it is flagged as an error by the interface. For example, this error may indicate data corruption.
Out CLP	Number of Packets and/or cells where the Output Cell Loss Priority bit is set.
OutAS	Number of autonomous-switched or silicon-switched output packets.
OAM cells received	Number of OAM cells received on this VC.
