Hello, i am a german guy, so please excuse my bad english. I have a question about static MAC addresses on a WS-C3750G-48TS Switch. I have no static adresses configured on my switch, but see some when execute the "show mac address-table static" command. And i mean not the 0000.0c07.ac01 addresse for HSRP, Spanning-tree or something else, which are forwarded to the CPU, i mean entries like this:   Switch#show MAC address-table interface g2/0/47           Mac Address Table ------------------------------------------- Vlan    Mac Address       Type        Ports ----    -----------       --------    -----    3    1212.1212.1212    STATIC      Gi2/0/47    3    1414.1414.1414    STATIC      Gi2/0/47 Total Mac Addresses for this criterion: 2 This entries not configured or dynamicly learned. I suspected functions like gratitious-arp, but this is only for IP<->MAC translation. Then i have searched functions like gratitious-mac or mac-notification. I have searched for a function with tells the switchport: "Hey, that is my MAC address. There is no need to learn this address dynamicly", but with no luck. Does anybody can tell me, why these MAC addresses are shown static, and not dynamicly?   Thanks for help. Thomas ... View more

Hi all, ACS5.4 is the first ACS5.* version which support multiple Ethernet Interfaces for AAA authentication. Cisco explained, that only one interface can be used as management interface. This interface is always eth0. http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_system/5.4/release/notes/acs_54_rn.html#wp225769 I have tested this with an VMware machine and two interfaces. In my environment it is possible to connect via ssh and authenticate via tacacs and raduis on both interfaces. The management web-gui is only available in interface eht1, and not what cisco explained. I have searched many cisco documents, to find out how to configure the primary web-gui interface, but i always found the explanation that this will be eht0. Has anyone an idea how to switch this? Thanks for help. ... View more

Hi, i have a Question to Router RAM usage. My Router have 512MB of Memory. When i do a "show version" I get this otput: Cisco ********* processor with 491520K/32768K bytes of memory. This means 491MB for CPU and 32MB for IO. Now i do a "show memory" and get this output:                 Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b) Processor   6353EB60   430707644    14276428   416431216   416363448   413930428       I/O    E000000    33554432     1884520    31669912    31669912    31669884 Now here are only 430MB Total RAM for the Processor. Why this? What is with the other 60MB Memory? How does these values are in context with the Output of a  "show region"? Region Manager:       Start         End     Size(b)  Class  Media  Name 0x0E000000  0x0FFFFFFF    33554432  Iomem  R/W    iomem 0x60000000  0x7DFFFFFF   503316480  Local  R/W    main 0x60008EF8  0x6204F18B    33841812  IText  R/O    main:text 0x62050000  0x6303FE1F    16711200  IData  R/W    main:data 0x6303FE20  0x6353EB5F     5238080  IBss   R/W    main:bss 0x6353EB60  0x6453EB5F    16777216  Local  R/W    main:heap 0x7D000000  0x7DFFFFFF    16777216  Local  R/W    main:heap 0x7E000000  0x7FFFFFFF    33554432  Iomem  R/W    iomem:(iomem_cwt) 0x80000000  0x8DFFFFFF   234881024  Local  R/W    main:(main_k0) 0xA0000000  0xADFFFFFF   234881024  Local  R/W    main:(main_k1) Thank in advance Thomas ...

Hi, i want to create a backup from my ACS Server with a custom name. When i create a backup and enter ACSBackup as the filename prefix and backup is run on August 07, 2012 at 20:37 hours, then ACS creates the backup file InstanceName-ACSBackup-120807-2037.tar.gpg. But i want a format like this: InstanceName-ACSBackup-2012_08_06.tar.gpg. Is this possible with a kind of variable name like ACSBackup-%year%_%month%_%day%.tar.gpg to change the complete name of the Backup file? Thomas ... View more
