BRIDGE-MIB for Layer 2 Ethernet Switching
Simple Management Network Protocol (SNMP) development and use is centered around the Management Information Base (MIB). An SNMP MIB is an abstract data base, i.e., a conceptual specification for information that a management application may read and modify in a certain form. This does not imply that the information is kept in the managed system in that same form. The SNMP agent translates between the internal data structures and formats of the managed system and the external data structures and formats defined for the MIB.
The Layer 2 Ethernet Switching Interface BRIDGE-MIB is supported in the Cisco 1861 platform from the release 15.0 (1) XA. The BRIDGE-MIB enables the user to know the Media Access Control (MAC) addresses and spanning tree information of the Ethernet switch modules. The user can query the MIB agent using the SNMP protocol and get the details of Ethernet switch modules such as MAC addresses of each interfaces and spanning protocol information.
The Bridge-MIB uses the following approaches to get the L2 layers BRIDGE-MIB information:
•
•
In the community string based approach, one community string is created for each VLAN. Based on the query, the respective vlan MIB is displayed.
To get the BRIDGE-MIB details, use the snmp-server community public RW command in the Configuration mode.
Router(config)#snmp-server community public RW
Use the following syntax to query the SNMP BRIDGE-MIB details.
snmpwalk -v2c <ip address of the ISR, ...> public .1.3.6.1.2.1.17snmpwalk -v2c <ip address of the ISR, ...> public@2 .1.3.6.1.2.1.17snmpwalk -v2c <ip address of the ISR, ...> public@3 .1.3.6.1.2.1.17
Note
In the context based approach, the SNMP context mapping commands are used to display the values for L2 interfaces information. Each VLAN is mapped to a context. When the user queries with a context, the MIB displays the data for that specific VLAN, which is mapped to the context. In this approach, each vlan is manually mapped to a context.
To get the BRIDGE-MIB details, use the following commands in the Configuration mode.
Router(config)#Routersnmp-server group public v2c context bridge-groupRouter(config)#snmp-server community public RWRouter(config)#snmp-server community private RWRouter(config)#snmp-server context bridge-groupRouter(config)#snmp mib community-map public context bridge-groupUse the following syntax to query the SNMP BRIDGE-MIB details.
snmpwalk -v2c <ip address of the ISR, ...> public@1 .1.3.6.1.2.1.17 ?L2-MIBsnmpwalk -v2c <ip address of the ISR, ...> private .1.3.6.1.2.1.17?L3-MIB
Note
For more details to configure and retrieve the BRIDGE-MIB details, see the Technical Notes at
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a9b.shtml#brgmib

Open Caveats - Cisco IOS Release 15.0(1)XA5
There are no open caveats in this release.
Resolved Caveats - Cisco IOS Release 15.0(1)XA5
Note
CSCth03022 Crafted SIP packets may cause device to reload.Multiple vulnerabilities exist in the Session Initiation Protocol (SIP) implementation in Cisco IOS Software and Cisco IOS XE Software that could allow an unauthenticated, remote attacker to cause a reload of an affected device or trigger memory leaks that may result in system instabilities. Affected devices would need to be configured to process SIP messages for these vulnerabilities to be exploitable.
Cisco has released free software updates that address these vulnerabilities. There are no workarounds for devices that must run SIP; however, mitigations are available to limit exposure to the vulnerabilities.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20110928-sip.shtml.
CSCti33534 "no ipv6 address autoconfig" may cause crash after router advert flood.Symptom After launching a flood of random IPv6 router advertisements when an interface is configured with ''ipv6 address autoconf'', removing the IPv6 configuration on the interface with ''no ipv6 address autoconf'' may cause a reload. Other system instabilities are also possible during and after the flood of random IPv6 router advertisements.

CSCsx67255 ISDN call failure with cause 47 after DSP allocation failure on channel.Symptom An outgoing call from an IP phone to PSTN through ISDN PRI fails on a channel due to a DSP allocation failure (not enough DSPs to support the call). Subsequent calls through that same channel continue to fail with "resource unavailable" cause value equal to 47 even after DSP resources have been made available to handle the call.
Conditions
DSP allocation failures on gateway can be checked through the use of the exec command show voice dsp group all. The last line of the show command output includes a counter for "DSP resource allocation failure".
This issue can also be seen in some cases upon bootup. When a gateway is reloaded, system resources will come up with a slightly different timing. If, for example, a PRI interface comes up before the DSP resources have fully initialized, there may be a similar failure.

CSCsz52576 vlan.dat file lost after second power cycle - VTP Domain Name disappears.Symptom The vlan.dat file gets deleted after the second reload of the router, and the VLAN definition and names are lost (not the interfaces and IP addresses). It has been observed that when the vlan.dat is lost, in sh vtp status, the VTP Domain Name is blank (and was properly configured before).
Conditions
Workaround
Further Problem Description: When a customer is running an image that does not store the VTP and VLAN information in the start-up configuration or the normal output of show running-config, the vlan.dat file gets overridden to the default vlan.dat approximately 2 minutes after reboot. The current VLANs and VTP information remains operational until the router is rebooted.
A reboot causes the VLANs and VTP information to disappear because the start-up configuration does not contain any VLAN or VTP information, nor does the vlan.dat file in flash.
The operating VTP information appears in the output of show running-config all (which shows non-default and default values), indicating that the router considers the VTP information to be at default values even when there is a VTP domain name configured. This allows the VLANs and VTP to remain operational until the router is rebooted.

CSCsz92704 Voice GWs not supporting DSPfarm services should provide warning message.Symptom IOS Voice GateWay (VGW) platform families like the IAD2430, VG224, VG202, and VG204 are fixed form-factor VGWs which have C5510 DSPs soldered onto the mainboard. As such they are not expandable to install extra DSP resources and are meant primarily as TDM-IP devices. Nonetheless in most IOS releases it is possible to configure dsp services dspfarm under the voice-card 0 CLI in the running-config as well as to set dspfarm profile N <conference|transcode> even though transcoding and conferencing services are not supported on these platforms. There aren't enough DSPs available to make these DSP services viable in addition to accommodating regular TDM-IP VoIP calls.

CSCta14536 Router crash pointing to SYS-6-STACKLOW on IPIPGW.Symptom A Cisco IOS VoIP gateway configured for IPIPGW (CUBE) functionality may crash.
Conditions
This has been found to occur in some scenarios where a single voip call loops (meaning the call is from the IPIPGW back to the same IPIPGW) through the IPIPGW.
When this occurs, the following error message may be noticed:
%SYS-6-STACKLOW: Stack for process IP Input running low, 0/12000Workaround
The other possible workaround is to introduce another termination point in the RTP packet flow beside the IPIPGW. For example, if interworking with Cisco Unified Communications Manager (Callmanager) a MTP resource may be used to prevent this loop as long as the MTP resource is not the CUBE gateway.
CSCta16495 IOS should warn if no DSP resources exist for voice-port at bootup.Symptom When the router boots up, voice ports that require DSPs like FXO and FXS cards do not show up in the running configuration.
