I setup as described on this page, when nxos boot, I get loader prompt and i run command boot nxos.7.0.3.I7.4.bin.
But every time I press enter, it adds an extra carriage return and this is messing up initial config as yes to abort auto provisioning also feeds carriage return to setup secure paasword and then when setting initial password and enter, will also feed a carriage return to confirmation password making confirmation password blank and it wont let me abort.
How do I get rid/fix extra carriage return?
Any help is appreciated.

I know this is old but I was running into this issue as well with the built-in Windows telnet client that would auto launch my console session when using Chrome or Edge. I switched to Firefox and it gave me a prompt to select a handler for the telnet connection, I was able to switch it to PuTTY which seems to handle the carriage returns correctly.

I’ve followed the steps exactly but I have my own image – nxosv.9.2.3.qcow2. When I go to open up program, it just hangs. I waited overnight. It is set to defaults – 2 cpu, 8192 memory, etc… I even changed the name as the instructions state from nxosv,9.2.3.qcow2 to sataa.qcow2 but the switch won’t stay on unless I either capitalize the S in sataa.qcow2 or add nxosv9k-sataa.qcow2 to the Linux name. I’ve fixed permissions a dozen times. I even tried VNC instead of putty or secureCRT. VNC just states not boot. Both putty and secureCRT just hangs there when I have the Sataa.qcow2 or nxosv9k-sataa.qcow2 applied. Can someone please help me out? I’ve tried on two different laptops. One laptop I have the vL2/L3 configure. This one I don’t have configured but same thing happens. I need to create a lab for VPC configuration between several pairs of L3 switches.

What is NTP and syslog? ›Syslog messages can be time- stamped for analysis of the sequence of network events; therefore, it is important to synchronize the clock across the network devices with a Network Time Protocol (NTP) server. In this lab, you will configure R1 as the NTP server and R2 as a Syslog and NTP client.
What is the 192.168 0.0 IP address? ›
0.0 is the starting point of the reserved private network space that encompasses all IP addresses through the 192.168. 0.0-192.168. 255.255 range.
What are the 4 types of IP address? ›An internet protocol (IP) address allows computers to send and receive information. There are four types of IP addresses: public, private, static, and dynamic.
What are the 4 numbers in an IP address? ›An IP address has two parts: the network ID, comprising the first three numbers of the address, and a host ID, the fourth number in the address. So on your home network — 192.168. 1.1, for example – 192.168. 1 is the network ID, and the final number is the host ID.
What is admin default password? ›#2) Generally, for most of the routers, the default username and password is “admin” and “admin”. However, these credentials may vary depending upon the maker of the router.
What is the default user password? ›Default passwords are intended to be placeholders and used only for the initial setup of hardware or after a factory reset. The user enters the password and is usually prompted to change it as part of the process, but not always. Examples of default passwords include admin, password and guest.

- Flowchart:
To connect, use the NEXUS Server's internal address ( http://localhost:9780 , using the default port number ) or its network address ( http://<computername>:9780 – where < computername > is the NEXUS Server host PC's network name, and using the default port number).
What is the maximum number of external syslog servers? ›You can configure up to 10 external syslog backup servers.
Can there be more than one syslog server profile? ›
Configure a Syslog server profile
You can use separate profiles to send syslogs for each log type to a different server. To increase availability, define multiple servers (up to four) in a single profile.
devices. syslog to monitor and troubleshooting Cisco devices.” that output goes nowhere. There are eight different logging levels.
How many vPC can be configured in Nexus switches? ›The maximum number of switches in a vPC domain is two. The maximum number of vPC peers per switch or VDC is one. When Static routing from a device to vPC peer switches with next hop, FHRP virtual IP is supported. Dynamic routing adjacency from vPC peer switches to any Layer3 device connected on a vPC is not supported.
What syslog stands for? ›System Logging Protocol (Syslog) is a way network devices can use a standard message format to communicate with a logging server. It was designed specifically to make it easy to monitor network devices. Devices can use a Syslog agent to send out notification messages under a wide range of specific conditions.
Which is better syslog ng or Rsyslog? ›Rsyslog is mainly available for Linux and recently for Solaris. The syslog-ng application is highly portable and available for many more platforms including AIX, HP-UX, Linux, Solaris, Tru64 and most variants of BSD.
