Re: AppleTalk on Support exam [7:269]
Priscilla, I took the CIT test on Wednesday. There were about three AppleTalk questions. Mainly, which debug commands to issue to monitor different AppleTalk zone registrations and what not. I wouldn't sweat it too much.

CCIE R&S Lab Locations [7:46904]
Quick question for everyone. In which cities is the CCIE Routing and Switching Lab exam offered? I have heard various stories from different places and the only official city that I can find on cisco.com is San Jose. Is the exam proctored in RTP, North Carolina also?

Interesting terminal server issue [7:48247]
Hey guys, I have a home lab setup for my CCIE studies and I have been bumping into a random issue with my terminal server. I have a 2509 that I use with an Octal cable to connect to my routers and switches. Frequently I will see a line go hot without me having initiated a session (I see an asterick by the line in 'show lines'). If I clear the line using 'clear line x' and then open a session to that device I will get about a hundered lines of trash thrown to the end device as input. Once the trash scrolls by and errors out, I have regular prompt access to the router with no further issues. This is not an all the time thing, but it is fairly frequent. Here's my setup on the terminal server: ip host r1 2001 1.1.1.1 ip host r2 2002 1.1.1.1 ip host r3 2003 1.1.1.1 ip host r4 2004 1.1.1.1 ip host s1 2005 1.1.1.1 ip host s2 2006 1.1.1.1 ! interface Loopback0 ip address 1.1.1.1 255.0.0.0 ! line 1 8 transport input all And here's the config for one of my end routers: line con 0 transport input none I'm using an authentic Cisco octal cable that appears to be shielded and since the garbage only occurs randomly and at initial connection I have ruled out interference. Any help is appreciated Thanks, Don Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=48247&t=48247 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Interesting terminal server issue [7:48247]
Hey guys,
Good call Jason, added 'no exec' on the term server and haven't seen
the issue since.
Thanks

DHCP Server on Multiple VLANs [7:49403]
Hey guys, I have a Cisco 3620 connected to a 2948G-L3 which in turn provides layer three services to a cluster of 3548XLs. I have 9 operating VLANs and have been trying to work out a scenario for DHCP in my environment. Right now, we assign static IPs in all 9 vlans because we do not want to provide seperate DHCP servers for each. If we could find a way to get one server to provide DHCP to all the VLANs then we could implement it. The trick is, each VLAN is a different subnet. I had heard that if you use the 3620 as a DHCP server, create subinterfaces on a FE port using ISL and assign IP addresses appropriately, and create multiple DHCP pools, then the router would issues IPs from pools that matched the interface it drew the request from. However, when I try this it just issues IPs from the first pool until it is full and then moves to the next. Is there a way to make sure the router assigns correct IPs on the correct sub-interfaces? Is there a 3rd party DHCP server that would do this better? Let me do a sample config to show what I tried. Each network has a network printer at .200 (don't ask) and a router sub-interface at .1 except the 10.10.10.0 network which has reserved IPs through 100, but still a router interface at .1 Here's the Cisco 3620 DHCP portion of the config: ! ip dhcp excluded-address 10.10.10.1 10.10.10.100 ip dhcp excluded-address 192.168.1.1 ip dhcp excluded-address 192.168.1.200 ip dhcp excluded-address 192.168.2.1 ip dhcp excluded-address 192.168.2.200 ip dhcp excluded-address 192.168.3.1 ip dhcp excluded-address 192.168.3.200 ip dhcp excluded-address 192.168.4.1 ip dhcp excluded-address 192.168.4.200 ip dhcp excluded-address 192.168.5.1 ip dhcp excluded-address 192.168.5.200 ip dhcp excluded-address 192.168.6.1 ip dhcp excluded-address 192.168.6.200 ip dhcp excluded-address 192.168.7.1 ip dhcp excluded-address 192.168.7.200 ip dhcp excluded-address 192.168.8.1 ip dhcp excluded-address 192.168.8.200 ! ip dhcp pool Vlan1 network 10.10.10.0 /24 dns-server 4.2.2.1 default-router 10.10.10.1 ! ip dhcp pool Vlan10 network 192.168.1.0 /24 dns-server 4.2.2.1 default-router 192.168.1.1 ! ip dhcp pool Vlan20 network 192.168.2.0 /24 dns-server 4.2.2.1 default-router 192.168.2.1 ! ip dhcp pool Vlan30 network 192.168.3.0 /24 dns-server 4.2.2.1 default-router 192.168.3.1 ! ip dhcp pool Vlan40 network 192.168.4.0 /24 dns-server 4.2.2.1 default-router 192.168.4.1 ! ip dhcp pool Vlan50 network 192.168.5.0 /24 dns-server 4.2.2.1 default-router 192.168.5.1 ! ip dhcp pool Vlan60 network 192.168.6.0 /24 dns-server 4.2.2.1 default-router 192.168.6.1 ! ip dhcp pool Vlan70 network 192.168.7.0 /24 dns-server 4.2.2.1 default-router 192.168.7.1 ! ip dhcp pool Vlan80 network 192.168.8.0 /24 dns-server 4.2.2.1 default-router 192.168.8.1 ! interface FastEthernet1/0 description connected to Private Network no ip address duplex auto speed auto ! interface FastEthernet1/0.1 encapsulation isl 1 ip address 10.10.10.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.10 encapsulation isl 10 ip address 192.168.1.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.20 encapsulation isl 20 ip address 192.168.2.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.30 encapsulation isl 30 ip address 192.168.3.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.40 encapsulation isl 40 ip address 192.168.4.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.50 encapsulation isl 50 ip address 192.168.5.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.60 encapsulation isl 60 ip address 192.168.6.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.70 encapsulation isl 70 ip address 192.168.7.1 255.255.255.0 no ip redirects ! interface FastEthernet1/0.80 encapsulation isl 80 ip address 192.168.8.1 255.255.255.0 no ip redirects !

RE: Interesting Situation with a 2948G-L3 and Inter-VLAN [7:51249]
I ran a bandwidth monitor between six stations on one VLAN and six stations on a second VLAN to see what kind of latency, packet loss, and throughput I could get on the stations. I found I could easily get six separate communication streams going with each absorbing 25Mbits of bandwidth which would have more than saturated the 3620 so I am definitely seeing performance improvements over the old configuration. Now it's just a matter of tracking down my dropped link issue.
