Looking for a CCIE lab partner in New York City area
I'm looking for lab partner in the New York City area. I currently have 6 routers that handle 85% of the interfaces for the CCIE. I'm also using bootcamp labs for prep.

Point to Point T1 connectivity
I have a problem. I have a point to point t1 router 1Line up protocol down router 2 Line down protocol down On router 2 the alarm LED is on. Both routers shared the same circuit configs. Router 1 clocking is internal and router 2 clocking is line. Should the cables from the demark be straight through? One straight through? One crossed? Any advice would be greatly appreciated.

Point to Point Link Problem
I have a point to point T1 that is not working. The routers involved are a 3640 and a 2610. I have configured the routers with the same line code, framing, etc. The WICs are internal. The telco can loopup to the 2610 but not the 3640. I've swapped cables and the internal WIC on the 3640 side. Any recommendations would be greatly appreciated. 3640: 3640#sh int s0/1 Serial0/1 is down, line protocol is down Hardware is DSCC4 with integrated T1 CSU/DSU Internet address is 10.1.2.1/30 MTU 1500 bytes, BW 2048 Kbit, DLY 2 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation PPP, loopback not set Keepalive set (10 sec) LCP Closed Closed: IPCP, CDPCP Last input never, output never, output hang never Last clearing of "show interface" counters 00:07:40 Input queue: 0/75/0 (size/max/drops); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/0/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 packets output, 0 bytes, 0 underruns 0 output errors, 0 collisions, 1 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions DCD=down DSR=up DTR=up RTS=up CTS=down 3640#sh service-module s0/1 Module type is T1/fractional Hardware revision is 0.96, Software revision is 0.2, Image checksum is 0xED22BEC5, Protocol revision is 0.1 Transmitter is sending remote alarm.

IP Helper-address questions [7:247]
I have two routers connected via serial point to point link. Router 1 has an ethernet segment with PDC info I want forwarded to Router 2 ethernet segment. No ip directed broadcast is configured on all interfaces. I want netbios traffic passed from one segment to the other. I have placed an IP helper-address statement on the ethernet interface needing the help. Do I need to use the ip helper-address on all interfaces to the source ip helper-address? Is the ip forward-protocol also necessary?

[7:9493] Can you explain to me how you can telnet into the router if "all interfaces fail" with the exception of the loopback interface? If ALL interfaces fail, the only way you can get to the router is via console or AUX. And you call yourself a CCNP. No wonder the value of Cisco certification value (with the exception of the CCIE) is becoming less desirable these days.

High FCS errors on cat5505 [7:15885]
Hello. I'm experiencing huge amounts of fcs errors on my switch. 3/1 91521 fcs errors 3/2 28078 fcs errors These counters were cleared Friday. I understand that these errors are usually media related. I've swapped cables so far which has not seemed to help. I can tell you there is a sun e450 and e250 attached to these ports. Do you know of any interoperability issues with the cat 5505 and sun NICS?
