Table 1 lists the memory and IOS Software requirements for the Cisco 880VA Series Multimode VDSL2/ADSL2/2+ DSL platforms, using firmware Release A2pv6C035d.d23j.
Note
This firmware version is compiled with the SDK version 4.02L.03 and supports IOS release 15.6(2)T and earlier releases up to the supported version mentioned in the firmware release note. This firmware is not supported with Cisco IOS 15.6(3)M version and later releases.
Determining the Firmware Version
To determine the version of firmware currently running on your Cisco 880VA series router, issue the following IOS command and look for the output in BOLD:
Upgrading to a New Firmware Release
Perform the following steps to upgrade to a new firmware release:
1. Download the new firmware from Cisco.com Software Center, at http://www.cisco.com/cisco/web/download/index.html
Choose Routers -> Branch Routers -> Cisco 800 Series Routers -> Cisco 887VA Integrated Services Router -> Very High Bitrate DSL (VDSL) Firmware
2. Copy the firmware to a designated location; for example router flash, or a TFTP server.
3. Configure the router to load the new firmware from a designated location.
4. Restart the controller interface for the new firmware to take effect
Modem Settings
New modem commands are introduced with the release of the A2pv6C032b.d23b firmware and IOS release 15.1(2)T to allow custom configurations of DSL modem settings to ensure DSL interoperability in different environments. Please consult your Service Provider on required modem settings (if any) for the particular SP's network.
Before you enable the modem settings, you must execute the "service internal" command in CONFIG mode. For example:

- "Support CIPolicy in G.993.2
- G.INP mode in 30a mode is not supported yet
- G.INP supports DTU framing type 1 only
- US PhyR in 30a mode has stability issue in certain loops with no delay queue feature enabled against BRCM CO FW version 10.3.1 and older. The issue has been fixed and the fix will be in future CO FW releases
- US SRA with dynamic D may have excessive CRCs under certain conditions with q = 2 against BRCM CO FW version 10.3.4 and older. The issue has been fixed and the fix will be in future CO FW releases
- US SRA with dynamic D may have excessive CRCs under certain conditions with q = 2 against BRCM CO FW version 10.3.4 and older. The issue has been fixed and the fix will be in future CO FW releases
- G.INP supports DTU framing type 1 only
- G.vector shall be used with BRCM CO VE_10_7_2 and later.
- In vectoring mode, non VDSL protocols should be disabled; SRA should be enabled from driver side.V43 should be disabled by setting CfgFlagsDisableV43 (0x10000) in pG993p2Cap->cfgFlags.
- The performance of G993.2 and G.992.[35] with impulse noise in training can improved by setting kPhyCfg1EnableImpFiltInArqMode (0x00000001) driver bit for G.INP/PhyR tests and kPhyCfg1EnableImpFiltInFecMode driver bit (0x00000002) for non-G.INP/PhyR tests. These driver bits are set in DslPhyCfg5 parameter.
- Rate selection will reduce achieved DS delay in ADSL modes by setting pDslCmd->param.dslModeSpec.capabilities.auxFeatures in BcmAdslCoreSetConnectionParam() to kDslG992p5MinimizeDSDelay.
- Rate variation in VDSL2 against Alcatel NVLT-C DSLAMs with CO5 FW 1.0.9r48b. The issue is not observed with newer FW versions. This can be worked around by changing pG993p2Cap->cfgFlags in BcmAdslCoreSetConnectionParam() of ADSL driver file BcmAdslCore.c. The change is to set pG993p2Cap->cfgFlags to CfgFlagsAlignAfterPeriodics (0x20) instead of default value of 0.
- Rate variation may happen in VDSL2 against Alcatel NVLT-C DSLAMs with Ikanos chipset in Auto Profile mode. This can be worked around by changing pG993p2Cap->cfgFlags in BcmAdslCoreSetConnectionParam() of ADSL driver file BcmAdslCore.c. The change is to set pG993p2Cap- >cfgFlags to CfgFlagsNoG994AVdslToggle (0x10) instead of default value of 0.
- ANSI T1.413 is disabled by default. It can be turned on by setting the modCfg in BcmAdslCoreSetConnectionParam() to kAdslCfgModGdmtOnly | kAdslCfgModGliteOnly | kAdslCfgModT1413Only.
- ATM/PTM configuration for all modes can be set using adsl configure - TpsTc <0xBitMap-AvPvAaPa>. Value 0 means default (same as 0xE) where ATM/PTM are enabled for VDSL2 modes but only ATM is enabled for ADSL modes.
- Alternative ATTNDR calculation in G993.2 which accounts for INP, delay and available interleaving memory can be enabled by changing pG993p2Cap->cfgFlags in BcmAdslCoreSetConnectionParam() of ADSL driver file BcmAdslCore.c. The change is to set pG993p2Cap->cfgFlags to CfgFlagsEnableATTNDRframingConstrains (0x8000) instead of default value of 0.
- CPE sometimes connects in T1.413 mode against certain multimode DSLAMs with G.DMT enabled. This issue can be resolved by setting pDslCmd->param.dslModeSpec.capabilities.auxFeatures in BcmAdslCoreSetConnectionParam() to kDslHsPreferGdmtOverT1p413(0x80000).
- The performance of G.992.[35] with impulse noise in training can improved by setting kPhyCfg1EnableImpFiltInArqMode (0x00000001) driver bit for G.INP/PhyR tests and kPhyCfg1EnableImpFiltInFecMode driver bit (0x00000002) for non-G.INP/PhyR tests. These driver bits are set in DslPhyCfg5 parameter.
- Rate variation may happen in VDSL2 against Alcatel NVLT-C DSLAMs with Ikanos chipset in Auto Profile mode. This can be worked around by changing pG993p2Cap->cfgFlags in BcmAdslCoreSetConnectionParam() of ADSL driver file BcmAdslCore.c. The change is to set pG993p2Cap->cfgFlags to CfgFlagsNoG994AVdslToggle (0x10) instead of default value of 0.
- ATM/PTM configuration for all modes can be set using adsl configure -TpsTc <0xBitMap-AvPvAaPa>. Value 0 means default (same as 0xE) where ATM/PTM are enabled for VDSL2 modes but only ATM is enabled for ADSL modes.
- Alternative ATTNDR calculation in G993.2 which accounts for INP, delay and available interleaving memory can be enabled by changing
- pG993p2Cap->cfgFlags in BcmAdslCoreSetConnectionParam() of ADSL driver file BcmAdslCore.c. The change is to set pG993p2Cap->cfgFlags to CfgFlagsEnableATTNDRframingConstrains (0x8000) instead of default value of 0.
