We have deployed a large number of Cisco 897's.   If your ISP uses PPPoE it maxs out (aka runs out of CPU) around 160Mb/s.  If your ISP uses DHCP it gets up to around 190Mb/s.  This is when using it with the Gigabit Ethernet WAN port and a typical NAT + firewall configuration.   I'm not sure about 35b profile support.  I don't think we have ever had a customer that close.  The best connection I remember is about 70Mb/s on VDSL.  It definately supports profile 17a.     Note that the Cisco 897 has now been replaced by the 1100 series routers.  I found this document mentioned profile 35b support. https://www.cisco.com/c/en/us/td/docs/routers/access/1100/software/configuration/xe-16-7/cisco_1100_series_swcfg_xe_16_7_x/cisco_1100_series_swcfg_xe_16_7_x_chapter_010101.pdf ...

Not the answer you were looking for, but I would check out the Cisco Meraki MX68. https://meraki.cisco.com/products/appliances/mx68 Beautifull HTML5 GUI, excellent security features, and no stupid DHCP server limit. ... View more

You could still use them for sip calling routing and the like - but without any DSP resource you would have to be carefull with the codecs.   I bet no 1100 series will come out with analog ports, as analog ports are declining in use, greatly.  The small number required are now servde by ATA's. Just my crystal ball gazing. ... View more

@Leo Laohoo if I recall correctly, the 881V had 4 built in FXS ports.  I don't believe any 1100 series routers have FXS ports.  So they would need to go up to the 4000 series where you can get FXS modules. ... View more

Mostly yes, with AnyConnect being an exception (assuming this is a modern version of ASA software).  Really old versions everything had to be identical.   Note if you are replacing an ASA in a failover pair they must both be identical models.   If you have had an RMA unit you should be able to use the RMA licence transfer tool to transfer the licences from the old ASA to the new ASA. https://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/118000-technote-esa-00.html ...

I haven't got the answer.   I always thought that using MFA with 802.1x WiFi would be problematic.  For example, I would expect the user would need to re-authenticate everytime they roamed between APs.  And if you have someone in a fringe area dropping off and on they would need to keep authenticating.   I'll be watching your thread to see how it goes. ...

Try doing a "shut/no shut" on the port, and then check for an error in the log right afterwards. ... View more

That sounds fine to me.  I would also take a backup of the conifg off the current active unit to, "just in case".  Also you need to make sure the new unit is running the same software version as the current unit.   I typically copy the whole config off the standby to the primary and then just update the line " failover lan unit primary" and then plug them in. ...

Policy based routing only affects traffic flowing through the router.   You have to enable "Local Policy Based Routing" for it to affect traffic originating from the router. https://www.grandmetric.com/knowledge-base/design_and_configure/how-to-configure-policy-based-routing-for-localy-generated-traffic-cisco/ ...

I'm thinking you would need to jump up to an ISR4221 and then put whatever VoIP interface into it you need.   https://www.cisco.com/c/en/us/products/routers/4000-series-integrated-services-routers-isr/models-comparison.html   https://www.cisco.com/c/en/us/products/collateral/routers/4000-series-integrated-services-routers-isr/datasheet-c78-733646.html ...

@Mark Malone is right.   You can either get the firmware package as a "tar" file which you extract.  It creates that subdirectory you can see with the web interface, and it updates the boot environment. You can read about the process here (jump down to "Extracting a tar File"): https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-2_58_se/configuration/guide/2960scg/swiosfs.html#86987   Or you can just copy the boot file and update the boot environment yourself. ...
