Re: boot sequence [7:49174]
I posted this same question a few weeks back; you might find the posts there helpful. Also, you can look at this page: http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/cis4000/4000m/4000sig/vconfig.htm I am still uncertain of the answer, but have little time to research it further. I know, according to Cisco, if bit 13 of the register is not set, 0x102, theoretically, the router will boot: 1. To location specified in the boot statement in the config - if a statement exists, but the image can not be found, and all statements command a netboot, it will look for an image in flash, the boot to RMON if no image is in flash 2. If no boot statement, it will boot from network file - if no network file exists, the router will hang (because bit 13 not set) Add to this logic the idea that boot statements in config override the netboot sequence, and I am stuck with confusion about step 1 above. What happens if a boot statement exists, pointing to flash, but the image can not be found? Theoretically the router should hang if 0x102... however, when I tested it, the router defaulted to RMON. If you come up with a deifinitive answer, let me know.

You can. Just need to put the "ip helper-address" statement on those sub-ints. As long as the router can reach the DHCP server, so will the DHCP requests/replies. Hope this helps.

HSRP [7:47177]
Lets say I have HSRP configured on a series of routers... I know clients are sending packets to the MAC/IP of the well known "virtual MAC" with Cisco equipment. Assume the receiving station recieves the packet directly from the router participating in HSRP with the highest priority... what is the source MAC the receiving station sees?

Re: serial interface down/down or up/down [7:47101]
I have found a good bit of conflicting information on the causes of down/down and up/down. All agree that down/down can be caused by: 1. no cable connection 2. CSU/DSU powered down Some other reasons, although not consistently referenced in the literature are: 1. Faulty cable (may also cause up/down) 2. csu/dsu failure (not specify hardware or software)(may also cause up/down) 3. router serial int hardware problem 4. a DCE router interface will be down/down if DTR is not raised by the DTE device There are a plethora of reasons for up/down Not sure this clarifies, but hope it helps some Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=47136&t=47101 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: confreg [7:46924]

confreg [7:46924]
I understand the bit significance for the 16-bit confreg, but I am confused about the SEQUENCE of the boot and the issue with netboot. Assume confreg 0x2102, what is the correct boot sequence? Where does the flash overide (0x2-0xF) come into play i.e. does it replace the need to boot from the network or simply step in line before the attempt to netboot?

Re: Gigabit GBIC for 3550 [7:42680]

RE: What are the first thing you do...?? [7:42276]
Few questions... for the branch offices, how big are the subnets? If too big (i.e. larger than a single class C), may need to vlan... this also depends on the LAN traffic and apps (IPX SAPs, etc). The same routers that you use for WAN routing via the fractional T1's can perform inter-Vlan routing via sub-interfaces on the eth int (there may be some limitation if the IOS is old or you are dealing with leagcy equipment). BUT, remember it makes no sense to vlan if the benefit you gain from segmentation is outweighed by the extra overhead on the router... so you really need to analyze that LAN traffic. Also, the previous poster stated...check those port counters for errors, like FCS, CRC, etc. This may indicate cabling plant issues. Last, I would suggest using the "set port host" command instead of portfast on all ports not connected to other switches or routers. Hope this helps.

Re: 6509 and OC-3 ATM FlexWan [7:41904]

RE: 6509 and OC-3 ATM FlexWan [7:41904]
Running SRM is my choice as well. Can you point me to a Cisco documentation site for the config of the FlexWAN. I know you configure it through the MSFC, but looking for some examples (maybe some of your own). Also, what version of code have you done this with MADMAN? I see that before 12.1(3a)E4, FlexWAN would not take advantage of redumdant MSFC's, so in a failover case, the ATM config would not be copied over. Micheal...an FYI, we are still using the CatOS for switch and MSFC IOS for MSFC.

6509 and OC-3 ATM FlexWan [7:41904]
I have a choice here, and am not sure of the load probs. Core can be a 6509 with 2 MSFC 2's/SUPII's, with an uplink to a 7206 with an OC-3 ATM PA (MM)...OR, eliminate the 7206, get a Flexwan module for the 6509 and use the same OC-3 ATM PA. LAN side looks like this: 12 remote wiring closets, each having a 4006 with 4 48-port 10/100. Uplinks to 6509 via 1000SX GBICs (trunking). Mixed IP/IPX environment. 17 VLANS (IP and IPX), so the MSFC2's will be doing the inter-vlan routing. Route IPX on LAN with RIPv2, IPX on WAN with EIGRP. IP on WAN is OSPF.--> no choice here. WAN traffic mainly TN3270, web traffic and IPX (replication), plus OSPF routing updates. Suggestions? About a 11K savings on the non-7206 design.
