What type of LC's do you have in that router ? I'm trying to find what is the difference in the architecture between Eng3 vs Eng4 LC's that could justify this problem:
router#show ip cef resource Hardware resource allocation status summary Green (Normal), Yellow (Caution) Red (Alarm) Slot HW Resource Name Util Alert X E4_Lookup External SRAM 93 Y Y E3 Rx PLU 26 G Y E3_Rx_TLU 11 G Both have the same Route Memory and Packet Memory (512 Mb). But all i was able to find is related with Eng0/Eng1/Eng2: Cisco 12000 Series Internet Router Architecture: Line Card Design http://www.cisco.com/en/US/products/hw/routers/ps167/products_tech_note09186a00801e1dbd.shtml Thanks.
