Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

Sincerely, Charles Kozierok

Community-Based SNMP Version 2 (SNMPv2c) Message Format

This version of SNMPv2 was intended to keep the new protocol enhancements introduced by SNMPv2p but go back to the simple SNMPv1 security model. As such, the defining document for SNMPv2c, RFC 1901, specifies that its overall message format is the same as that of SNMPv1, except that the version number is changed. This is shown in Table 216 and Figure 281.
