2024年2月27日 · Hi All, I am upgrading Cisco ISR 4431 IOS from 17.3.3 to 17.9.4a. As per Cisco release notes below, recommended ROMMON from upgrade to 17.9.4a is 16.12 (2r) which we are already on but recommended CPLD version showing is 19042950.

2019年9月17日 · Hello, I don't see how your LAN can access the Internet through the ISR, since you are not even NATting the LAN range. Either create a Vlan 15 interface with an IP address on the 3850, or use a subinterface for the DMZ on the ISR: interface GigabitEthernet0/0/3.15 encapsulation dot1q 15 description DMZ Interface ip address 192.168.15.1 255.255.255.0 ip nat inside zone-member security DMZ ...

2024年11月30日 · Last week, I upgrade an ISR 1100 from 16.9.x to 17.12.x and I experienced the boot-loop-crash. There was no way to break into Rommon or boot up on the previous image on the ISR - We had to make a RMA to get a new ISR. On the other ISR 1100's, I went with the solution to upgrade to 17.9.x directly instead, which works fine.

2016年1月20日 · So we're finally replacing an old Cisco 2801 router with a fancy new ISR 4431. However we've been caught out, the old 2801 had access vlans assigned to physical interfaces and it seems this is a no-no on a 4431. Is our only solution to put in a switch module? Below is what we used to have. interfa...

2021年3月23日 · Hi, sorry for this simple question but I cannot find what is the MAX throughput licence you can buy for ISR4331. I have found info that 4431 is maxed at 500Mbit/s and 4331 is maxed at 300Mbit/s, is this correct ? show platform hardware throughput level The current throughput level is 300000 kb/...

2023年10月24日 · For some reason on the 4431 model we have inserted the USB stick with the file loaded on it, but we have no indication from the console output (after issuing a "term mon" on the SSH session we are monitoring the router with) that the USB stick was ever inserted.

2016年11月29日 · Cisco Support, Please kindly help to clarify the technical feasibility of the Cisco ISR 4431. Whether the built-in WAN/LAN port could be configured as switch port in dedicated access VLAN? Whether the built-in WAN/LAN ports could be …
