Cisco 4948-10ge Configuration Guide [patched]

I need to go through each word step by step, replacing each with three alternatives. Also, check for any HTML entities like "’" and correct them to proper punctuation. For example, "we’ve" should be "we've". However, the user might have wanted those as placeholders, but better to adjust for clarity. Also, the ampersand in "C4948-10GE(config-if)# switchport port-security" has "gigabitEthernet ⁄1" which should be a slash. Correct that first before applying replacements.

Putting it all together with the a format. Let me verify each term again to ensure three options and correct formatting. Also, make sure the output only includes the revised text, no extra explanations or headers as the user requested. Let me reconstruct each sentence with the synonyms now.

Wait, the user mentioned to keep brand names. So "Cisco 4948-10GE" and other brand-specific terms should stay as is. Also, commands like "dot1x" and "debug" are part of Cisco syntax, so changing those might not be appropriate. I need to avoid altering those commands. Let me look at each line. cisco 4948-10ge configuration guide

In the "Overview of the Cisco 4948-10GE" section, "1RU switch" might change to "1RU switch|compact rackmount|1U rackmount".

"High-performance computing environments" to "high-performance computing environments|data processing hubs|high-speed computing infrastructures".

For the features like "10 Gigabit Ethernet connectivity", alternatives could be "10 Gigabit Ethernet connectivity|10 GbE connectivity|10GbE uplinks". "IPv6 support" to "IPv6 support|IPv6 compatibility|IPv6 integration". "Robust security features" could become "robust security features|comprehensive security measures|enhanced security protocols".
