I assume this is the best place to post regarding IOS. We are beginning the process of upgrading our IOS images on 1841 and 2811 series remote routers. With the new 12.4.24.T2 code in advance enterprise the min. memory required is 256MB. Our routers contain 239MB as ordered. The code has loaded successfully on several test routers. My concern is there any long term effects of being below Cisco's recommended memory for the code.
Since we are below the requirement, what commands and statistics would you all suggest watching closely to ensure the stability of the router with its internal processes. The heaviest "load" we could put on the routers, config wise, will be with crypto maps, ZBF and WAAS
I look forward to your thoughts.
Cisco 2811 (revision 53.51) with 247808K/14336K bytes of memory.
247 + 14 = 261mb
Cisco 1841 (revision 5.0) with 235520K/26624K bytes of memory.
235 + 26 = 261mb
