same-security-traffic
To permit communication between interfaces with equal security levels, or to allow traffic to enter and exit the same interface, use the same-security-traffic command in global configuration mode. To disable the same-security traffic, use the no form of this command.
same-security-traffic permit {inter-interface | intra-interface}
no same-security-traffic permit {inter-interface | intra-interface}
Syntax Description
inter-interface
|
Permits communication between different interfaces that have the same security level.
|
intra-interface
|
Permits communication in and out of the same interface.
|
Defaults
By default, these behaviors are disabled.

2.2(1)

This command with the inter-interface keyword was introduced.
|
2.3(1)
|
Support for the intra-interface keyword was added.
|
Usage Guidelines
Allowing communication between same security interfaces (enabled by the same-security-traffic inter-interface command) lets you configure more than 101 communicating interfaces. If you use different levels for each interface, you can configure only one interface per level (0 to 100).
If you enable NAT control, you do not need to configure NAT between same security level interfaces.
The same-security-traffic intra-interface command lets traffic enter and exit the same interface, which is normally not allowed.

Note
We recommend that you do not make the outside interface (for example, where you access the Internet) on the same security level as your inside interfaces. On the FWSM, all connections have an associated xlate entry (even when you do not explicitly configure NAT). Xlates are normally created for connections between the inside interface and any lower security interface. In a same-security-traffic configuration, the FWSM randomly chooses which same-security interface is the "inside" interface for the sake of creating xlates. This selection may change later after a reload or after a software upgrade. If the FWSM considers the outside same-security interface as the "inside" interface, it creates xlates for every Internet host being accessed through it.
If there is any application (or a virus) on the internal network that scans thousands of Internet hosts, all entries in the xlate table may be quickly exhausted (see the Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide for xlate limits). After that, the FWSM will stop creating new xlates, logging error message %FWSM-3-305006: ("translation creation failed") for every new connection. The show resource usage command will show the number of active xlates equal or close to the limit. The clear xlate command will temporarily recover connectivity.
To avoid this situation, we recommend that the outside interface should always have security level lower than any other FWSM interface. This configuration guarantees that the FWSM always considers the ISP link as an outside interface. In this case, only one xlate will be created for every application or virus scanning Internet hosts from the inside network. No xlates will be created for Internet hosts being scanned.
Examples
The following example shows how to enable the same-security interface communication:
hostname(config)# same-security-traffic permit inter-interface
The following example shows how to enable traffic to enter and exit the same interface:
hostname(config)# same-security-traffic permit intra-interface

|
This command was introduced.
|
Usage Guidelines
This command is available for any host in an SDI AAA server group, but it is relevant only if the SDI version for the host is set to sdi-pre-5 in the sdi-version command. Prior to using this command, you must have configured the AAA server to use the SDI protocol.
The sdi-pre-5-slave command lets you identify an optional secondary server that is to be used if the primary server fails. The address specified by this command must be that of a server that is configured as a "slave" to the primary SDI server. In this situation, if you are using a pre-5 version, you must configure the sdi-pre-5-slave command so that the FWSM can access the appropriate SDI configuration record that is downloaded from the server. This is not an issue with version 5 and later versions.
Examples
The following example configures the AAA SDI server group "svrgrp1" that uses an SDI version prior to SDI version 5.
hostname(config)# aaa-server svrgrp1 protocol sdi
hostname(config-aaa-server-group)# aaa-server svrgrp1 host 192.168.10.10
hostname(config-aaa-server-host)# sdi-version sdi-pre-5

Usage Guidelines
Secure unit authentication provides additional security by requiring VPN hardware clients to authenticate with a username and password each time the client initiates a tunnel. With this feature enabled, the hardware client does not have a saved username and password.
Note
With this feature enabled, to bring up a VPN tunnel, a user must be present to enter the username and password.
Secure unit authentication requires that you have an authentication server group configured for the tunnel group the hardware client(s) use.
If you require secure unit authentication on the primary FWSM, be sure to configure it on any backup servers as well.
Examples
The following example shows how to enable secure unit authentication for the group policy named FirstGroup:
hostname(config)# group-policy FirstGroup attributes
hostname(config-group-policy)# secure-unit-authentication enable

security-level
To set the security level of an interface, use the security-level command in interface configuration mode. To set the security level to the default, use the no form of this command. The security level protects higher security networks from lower security networks by imposing additional protection between the two.
security-level number
no security-level
Syntax Description
number
|
An integer between 0 (lowest) and 100 (highest).
|
Defaults
By default, the security level is 0.
If you name an interface "inside" and you do not set the security level explicitly, then the FWSM sets the security level to 100 (see the nameif command). You can change this level if desired.

|
This command was introduced. It moved from a keyword of the nameif command to an interface configuration mode command.
|
Usage Guidelines
The level controls the following behavior:
•
Inspection engines—Some inspection engines are dependent on the security level. For same security interfaces, inspection engines apply to traffic in either direction.
–
NetBIOS inspection engine—Applied only for outbound connections.
–
OraServ inspection engine—If a control connection for the OraServ port exists between a pair of hosts, then only an inbound data connection is permitted through the FWSM.
•
Filtering—HTTP(S) and FTP filtering applies only for outbound connections (from a higher level to a lower level).
For same security interfaces, you can filter traffic in either direction.
•
NAT control—When you enable NAT control, you must configure NAT for hosts on a higher security interface (inside) when they access hosts on a lower security interface (outside).
Without NAT control, or for same security interfaces, you can choose to use NAT between any interface, or you can choose not to use NAT. Keep in mind that configuring NAT for an outside interface might require a special keyword.
•
established command—This command allows return connections from a lower security host to a higher security host if there is already an established connection from the higher level host to the lower level host.
For same security interfaces, you can configure established commands for both directions.
Normally, interfaces on the same security level cannot communicate. If you want interfaces on the same security level to communicate, see the same-security-traffic command. You might want to assign two interfaces to the same level and allow them to communicate if you want to create more than 101 communicating interfaces, or you want protection features to be applied equally for traffic between two interfaces; for example, you have two departments that are equally secure.
If you change the security level of an interface, and you do not want to wait for existing connections to time out before the new security information is used, you can clear the connections using the clear local-host command.
Examples
The following example configures the security levels for two interfaces to be 100 and 0:
hostname(config)# interface gigabitethernet0
hostname(config-if)# nameif inside
hostname(config-if)# security-level 100
hostname(config-if)# ip address 10.1.1.1 255.255.255.0
hostname(config-if)# no shutdown
hostname(config-if)# interface gigabitethernet1
hostname(config-if)# nameif outside
hostname(config-if)# security-level 0
hostname(config-if)# ip address 10.1.2.1 255.255.255.0
hostname(config-if)# no shutdown

Usage Guidelines
The service resetinbound command works with all inbound TCP connections whose access lists or uauth (user authorization) do not allow inbound connections. One use is for resetting identity request (IDENT) connections. If an inbound TCP connection is attempted and denied, you can use the service resetinbound command to return an RST (reset flag in the TCP header) to the source. Without the keyword, the FWSM drops the packet without returning an RST.
The FWSM sends a TCP RST to the host connecting inbound and stops the incoming IDENT process so that outbound e-mail can be transmitted without having to wait for IDENT to time out. The FWSM sends a syslog message stating that the incoming connection was denied. Without entering the service resetinbound command, the FWSM drops packets that are denied and generates a syslog message stating that the SYN was denied. However, outside hosts keep retransmitting the SYN until the IDENT times out.
When an IDENT connection times out, the connections slow down. Perform a trace to determine that IDENT is causing the delay and then enter the service command.
Use the service resetinbound command to handle an IDENT connection through the FWSM. These methods for handling IDENT connections are ranked from most secure to the least secure:
1.
Use the service resetinbound command.
2.
Use the established command with the permitto tcp 113 keyword.
3.
Enter the static and access-list commands to open TCP port 113.
When using the aaa command, if the first attempt at authorization fails and a second attempt causes a timeout, use the service resetinbound command to reset the client that failed the authorization so that it will not retransmit any connections. An example authorization timeout message in Telnet is as follows:
Unable to connect to remote host: Connection timed out
Examples
This example shows how to enable system services:
hostname(config)# service resetinbound

set connection
To set the maximum TCP and UDP connections or to enable or disable TCP sequence number randomization for a traffic class, use the set connection command in class configuration mode. The class configuration mode is accessible from the policy-map configuration mode. To remove these specifications, thereby allowing unlimited connections, use the no form of this command.
set connection {[conn-max number] [random-seq# {enable | disable}]}
no set connection {[conn-max number] [random-seq# {enable | disable}]}
Syntax Description
conn-max number
|
Sets the maximum number of simultaneous TCP and UDP connections.
|
disable
|
Turns off TCP sequence number randomization.
|
enable
|
Turns on TCP sequence number randomization.
|
random-seq#
|
Enables or disables TCP sequence number randomization. TCP initial sequence number randomization can be disabled if another in-line firewall is also randomizing the initial sequence numbers, because there is no need for both firewalls to be performing this action. However, leaving ISN randomization enabled on both firewalls does not affect the traffic.
Each TCP connection has two ISNs: one generated by the client and one generated by the server. The security appliance randomizes the ISN of the TCP SYN passing in the outbound direction. If the connection is between two interfaces with the same security level, then the ISN will be randomized in the SYN in both directions.
Randomizing the ISN of the protected host prevents an attacker from predecting the next ISN for a new connection and potentially hijacking the new session.
|
Defaults
For the conn-max keyword, the default value of number is 0, which allows unlimited connections.
Sequence number randomization is enabled by default.

Usage Guidelines
After you identify the traffic using the class-map command, enter the policy-map command to identify the actions associated with each class map. Enter the class command to identify the class map, and then enter the set connection command to set connections for that class map.
Note
When you identify a match access-list command for the class map, then the set connection actions are performed separately for each ACE in the access list and not for the access list as a whole. For example, you match an access list with 2 ACEs such as the following, and apply a connection limit of 2 connections:
access-list testACL extended permit tcp host 10.2.1.1 any eq 21
access-list testACL extended permit tcp host 10.2.1.1 any eq 23
match access-list testACL
set connection conn-max 2
The FWSM allows the creation of 2 connections for Telnet sessions (ACE 1) and 2 connections for FTP sessions (ACE 2).
Note
You can also configure maximum connections and TCP sequence randomization in the NAT configuration (the nat and static commands). If you configure these settings for the same traffic using both methods, then the FWSM uses the lower limit. For TCP sequence randomization, if it is disabled using either method, then the FWSM disables TCP sequence randomization.
Unlike the set connection command, NAT also lets you configure embryonic connection limits, which triggers TCP Intercept to prevent a DoS attack.
Examples
The following example configures the maximum number of simultaneous connections as 256 and disables TCP sequence number randomization:
hostname(config)# policy-map localpolicy1
hostname(config-pmap)# class local_server
hostname(config-pmap-c)# set connection conn-max 256 random-seq# disable

|
set connection timeout
To configure the timeout period after which an embryonic, half-closed, or idle TCP connection is disconnected, use the set connection timeout command in class mode. To remove the timeout, use the no form of this command.
set connection timeout {[embryonic hh:mm:ss] [half-closed hh:mm:ss] [tcp hh:mm:0]}
no set connection timeout {[embryonic hh:mm:ss] [half-closed hh:mm:ss] [tcp hh:mm:0]}
Syntax Description
embryonic hh:mm:ss
|
Defines the timeout period in seconds until an embryonic connection is closed, between 0:0:1 and 0:4:15. The default is 0:0:20. You can also set the value to 0, which means the connection never times out. Although you cannot set the maximum embryonic connections using the set connection command, you can set the timeout using this command.
|
half-closed hh:mm:ss
|
Defines the timeout period until a TCP half-closed connection is freed, between 0:0:1 and 0:4:15. The default is 0:0:20. You can also set the value to 0, which means the connection never times out. The FWSM does not send a reset when taking down half-closed connections.
|
tcp hh:mm:ss
|
Defines the idle time after which a TCP established connection closes, between 0:5:0 and 1092:15:0. The default is 0:60:0. You can also set the value to 0, which means the connection never times out.
Note This command ignores the value you set for seconds; you can only specify the hours and minutes. Therefore, you should set the seconds to be 0.
|
Defaults
The default embryonic connection timeout value is 20 seconds.
The default half-closed connection timeout value is 20 seconds.
The default tcp connection timeout value is 60 minutes.

Usage Guidelines
After you identify the traffic using the class-map command, enter the policy-map command to identify the actions associated with each class map. Enter the class command to identify the class map, and then enter the set connection timeout command to set connection timeouts for that class map.
Note
This command does not affect secondary connections created by an inspection engine. For example, you cannot change the connection settings for secondary flows like SQL*Net, FTP data flows, and so on using the set connection timeout command. For these connections, use the global timeout conn command to change the idle time. Note that the timeout conn command affects all traffic flows unless you otherwise use the set connection timeout command for eligible traffic.
Examples
The following is an example of a set connection timeout command that specifies a TCP connection timeout of two hours:

Usage Guidelines
The FWSM requires some initial configuration before ASDM can connect to it. Before you enter the setup command, you must first name an interface "inside" with the nameif command. The FWSM does not have a default inside interface.
Once you enter the setup command, you are asked for the setup information in Table 24-1.
Table 24-1 Setup Information
Prompt
|
Description
|

|
Enter yes or no. If you enter yes, the setup dialog continues. If no, the setup dialog stops and the global configuration prompt (hostname(config)#) appears.
|
|
Enter routed or transparent. The firewall mode prompt is available only in single mode or in a context.
|
|
Enter an enable password. (The password must have at least three characters.)
|
|
Enter the network interface IP address of the FWSM.
|
|
Enter the network mask that applies to the inside IP address. You must specify a valid network mask, such as 255.0.0.0, 255.255.0.0, or 255.255.x.x. Use 0.0.0.0 to specify a default route. You can abbreviate the 0.0.0.0 netmask as 0.
|
|
Enter the host name that you want to display in the command line prompt.
|
|
Enter the domain name of the network on which the FWSM runs.
|
IP address of host
running Device
Manager:
|
Enter the IP address on which ASDM connects to the FWSM.
|

|
Server Protocol
|
The server protocol for the server group specified by the aaa-server command.
|
Server Address
|
The IP address of the AAA server.
|
Server port
|
The communication port used by the FWSM and the AAA server. You can specify the RADIUS authentication port using the authentication-port command. You can specify the RADIUS accounting port using the accounting-port command. For non-RADIUS servers, the port is set by the server-port command.
|
Server status
|
The status of the server. You see one of the following values:
• ACTIVE—The FWSM will communicate with this AAA server.
• FAILED—The FWSM cannot communicate with the AAA server. Servers that are put into this state remain there for some period of time, depending on the policy configured, and are then reactivated.
You also see the date and time of the last transaction in the following form:
Last transaction ({success | failure}) at time timezone
date
If the FWSM has never communicated with the server, the message shows as the following:
Last transaction at Unknown
|
Number of pending requests
|
The number of requests that are still in progress.
|
Average round trip time
|
The average time that it takes to complete a transaction with the server.
|
Number of authentication requests
|
The number of authentication requests sent by the FWSM. This value does not include retransmissions after a timeout.
|
Number of authorization requests
|
The number of authorization requests. This value refers to authorization requests due to command authorization, authorization for through-the-box traffic (for TACACS+ servers), or for IPSec authorization functionality enabled for a tunnel group. This value does not include retransmissions after a timeout
|
Number of accounting requests
|
The number of accounting requests. This value does not include retransmissions after a timeout
|
Number of retransmissions
|
The number of times a message was retransmitted after an internal timeout. This value applies only to Kerberos and RADIUS servers (UDP)
|
Number of accepts
|
The number of successful authentication requests.
|
Number of rejects
|
The number of rejected requests. This value includes error conditions as well as true credential rejections from the AAA server.
|
Number of challenges
|
The number of times the AAA server required additional information from the user after receiving the initial username and password information.
|
Number of malformed responses
|
N/A. Reserved for future use.
|
Number of bad authenticators
|
The number of times that one of the following occurs:
• The "authenticator" string in the RADIUS packet is corrupted (rare).
• The shared secret key on the FWSM does not match the one on the RADIUS server. To fix this problem, enter the proper server key.
This value only applies to RADIUS.
|
Number of timeouts
|
The number of times the FWSM has detected that a AAA server is not responsive or otherwise misbehaving and has declared it offline.
|
Number of unrecognized responses
|
The number of times that the FWSM received a response from the AAA server that it could not recognize or support. For example, the RADIUS packet code from the server was an unknown type, something other than the known "access-accept," "access-reject," "access-challenge," or "accounting-response" types. Typically, this means that the RADIUS response packet from the server got corrupted, which is rare.

Usage Guidelines
An ACL only denies SYN packets, so if another type of packet comes in, that packet will not show up in the access-list hit counters. TCP packet types other than SYN packets (including RST, SYN-ACK, ACK, PSH, and FIN) are dropped by the FWSM before they can be dropped by an access list. Only SYN packets can create a session in the Adaptive Security Algorithm, so only SYN packets are assessed by the access list.
Examples
The following is sample output from the show access-list command:
hostname# show access-list
access-list cached ACL log flows: total 0, denied 0 (deny-flow-max 4096)
access-list 101; 10 elements
access-list 101 line 1 extended permit tcp any eq www any (hitcnt=0) 0xa14fc533

|
Usage Guidelines
The show activation-key command output indicates the status of the activation key as follows:
•
If the activation key in the FWSM Flash file system is the same as the activation key running on the FWSM, then the show activation-key output reads as follows:
The flash activation key is the SAME as the running key.
•
If the activation key in the FWSM Flash file system is different from the activation key running on the FWSM, then the show activation-key output reads as follows:
The flash activation key is DIFFERENT from the running key.
The flash activation key takes effect after the next reload.
•
If you downgrade your activation key, the display shows that the running key (the old key) differs from the key that is stored in the Flash (the new key). When you restart, the FWSM uses the new key.
•
If you upgrade your key to enable extra features, the new key starts running immediately without a restart.
•
For the PIX Firewall platform, if there is any change in the failover feature (R/UR/FO) between the new key and the oldkey, it prompts for confimation. If the user enters n, it aborts the change; otherwise it updates the key in the Flash file system. When you restart the FWSM uses the new key.
Examples
This example shows how to display the commands in the configuration for features that are enabled by your activation key:
hostname(config)# show activation-key
Serial Number: P3000000134 Running Activation Key: 0xyadayada 0xyadayada 0xyadayada
0xyadayada 0xyadayada
License Features for this Platform:
Maximum Physical Interfaces : Unlimited
Cut-through Proxy : Enabled
The flash activation key is the SAME as the running key.
