Network Switches (both layer 2 and 3)
Over time I have created small text files with info about different tasks regarding the switches. These were scratch notes at the time, but I am collecting them here for later review and reference.
Schema switch="switch" switchport= the switch port that a host is plugged in hostmac= the mac of the device connected to the switchport in this record. trunk ="trunk" if this is a trunk lobe. -------- Getting the ip/mac of an unmanaged switch; One way is to list the mac address table on the managed switches and look for ports with multiple mac addresses with are not links to other known switches. Then, using arp lookup and ping -a, you can find the ip address/dns names of the hosts connected to the unmanaged switches. When a switch reports more than one mac on a switch port could be another switch. If the number of macs is low, then it could be a host running a vm or proxy. Note that unmanaged switches use the MAC address, but do not have, use, or understand IP addresses. An IP address is used to access a device. So a switch which has software to allow settings, might need an IP address to let a user access its management system or web interface. But by definition, a dumb switch is never accessed that way by a user. -------- Check the ARP tables and see which ports have multiple MAC addresses in the ARP. You can then identify which switch that port goes to by seeing which switch has those addresses on discrete ports in its ARP table. when you look at the mac address table and see many mac addresses via a single port then that indicates it is an uplink. Start with the Cisco Switches and use show cdp neighbors this should show you which cisco switches are connected to eachother and show the local port and the remote port. This will at least get you the Cisco information. On Cisco type “SHOW CDP NEIGHBORS DETAIL” This will show you every Cisco device connected to the switch you are on and the port that connects it. What’s Connected Where? Go switch-by-switch. Log in with PuTTY/SSH. Go port-by-port & see what’s connected. Useful commands: • sh cdp nei (det) o This shows CDP-compliant Neighbors (Cisco equipment, Polycom phones, etc.) • sh mac add | i 0/24 o This gets a MAC address, if something is connected. Go port-by-port. • sh mac add | i 0cbd o This gets a port number from part of a MAC address. Investigate each MAC address: • DHCP on the Server o (hard to search – sort by Unique ID – might give Name) • On your PC o First ping subnet broadcast address, e.g. “ping 192.168.1.255” o “arp –a | find “a4-37-ee” (break last part of MAC into doublets with ‘-‘) • On a Switch or Router o First ping subnet broadcast address, e.g. “ping 192.168.1.255” o “sh arp | i a437” • MAC Address Lookup on the WWWeb o 1st 6 digits to show manufacturer (if arp & DHCP don’t help – may need to guess or touch these) <hr> Identify switches by HTTP headers ┌──(parth㉿Wintermute)-[~] └─$ nc -vv -n 127.0.0.169 80 (UNKNOWN) [127.0.0.169] 80 (http) open GET / HTTP/1.0 HTTP/1.1 302 Redirect Server: GoAhead-Webs Date: Sun Jul 30 22:37:32 2023 Connection: close Pragma: no-cache Cache-Control: no-cache Content-Type: text/html X-Frame-Options: SAMEORIGIN Location: http://Device/cs9e76935f/mts/config/log_off_page.htm <html><head></head><body> This document has moved to a new <a href="http://Device/cs9e76935f/mts/config/log_off_page.htm">location</a>.

Connect the switch to the computer using a standard 9-pin serial cable. The switch uses the factory default IP address of 192.168.1.254 by default. Enter the default login information: • Username is cisco • Default password is cisco (passwords are case sensitive 10 300 Series Managed Switches 115200 bits per second (with release 1.2.5 of the firmware, autobaud detection is enabled by default detect the speed after you press Enter • 8 data bits • no parity • 1 stop bit • no flow control ---[Reset at cli]--- https://www.cisco.com/c/en/us/support/docs/smb/switches/ cisco-small-business-300-series-managed-switches/ smb4985-administrator-password-recovery-for-300-and-500-series-manag.html Step 1. Access the CLI via a local console connection. Step 2. Power cycle the switch by unplugging the power cord and plugging it back in to the back of the device. After a couple of seconds you should see the Cisco ASCII logo with a prompt to escape the Autoboot loader. Press Return or Esc immediately to enter the Startup Menu. Note: Power cycle with the console cable and Putty connected. If the device goes into Autoboot sequence, you can reattempt to enter the Startup Menu by power cycling the device again. Step 3. Select menu item 3. Password Recovery Procedure Step 4. Press Enter to go back to the Startup Menu, and then press Esc to exit. This will start the Autoboot sequence. Step 5. After the switch has fully booted, you will be in password recovery mode. However, before changing any usernames or passwords, enter the following commands to avoid overwriting the existing configuration on the switch: Switch#enable Switch#copy startup-config running-config Note: In order to use backspace in the CLI, use the arrow keys to highlight the desired character and then hit Backspace to delete the character. You can also hold down Backspace to continuously delete characters to the right of the highlighted cursor. Step 6. In order to change the administrator password, you must enter configuration mode. To enter configuration mode, enter one of the following commands based on your access level: Switch(config)#username<new or previous username> privilege 15 password <new password> Switch(config)#username admin privilege 15 password password Note: Default password complexity settings require that the password contain at least 3 character classes such as a capital letter, a lowercase letter, and a number. Step 8. Enter the following commands to exit configuration mode and write to the configuration file. Switch#exit Switch#write Step 9. Enter Y to overwrite the startup configuration file. Step 10. Enter the following command to reboot the system so that you can log in with your newly configured username and password: Switch#reload Step 11. Enter Y to continue. Your device will then reboot. <hr> Switch Info 3q23 -------- This file deals with tracing each switch port to it's node. -------- UPDATE inventory SET datestamp = CURRENT_TIMESTAMP; -------- Article on resetting admin password; https://www.cisco.com/c/en/us/support/docs/smb/switches/ cisco-small-business-300-series-managed-switches/ smb4985-administrator-password-recovery-for-300-and-500-series-manag.html #:~:text=Simply%20press%20the%20Reset%20button,the%20default%20password%20of%20cisco.

You must have V1.3.7.18 installed before updating to V1.4.7.06. For Sx200/Sx300 models, first upgrade the device image to image version 1.3.5.x and upgrade the boot file to 1.3.5.06 You should upgrade your boot code to be 1.3.5.06 (you can find it in version 1.3.5.58 - in the zip file). Verify that you are on this boot code and then upgrade the firmware to 1.3.5.58, verify and final step upgrade to latest 1.4.9.4. In short, as you probably need to upgrade and your FW is below 135 or 137, use TFTP to upload sx300_boot-13506.rfb to update BOOT version first, then update your firmware... My tftp server ~/tftp/ https://www.baeldung.com/linux/tftp-server-install-configure-test <hr> Switch Port Assignments Notes on linking switch ports to the MAC of the host each is connected to. The idea is to gather this info from each switch and manually link them together. I will want to figure out an SSL connection to each, maybe. I also need to checkout using the Cisco serial console to gather the info that will allow me to add both a 'switchhome' and 'switchport' column in the DB to log which port (mac) each device is connected to and which port.
