    Cannot Ping ASA from 7204

    Thanks Burt that was my understanding, just wasn't sure with it having an access-group applied to the interface even though the access-list didn't exist... -Blue The significant problems we face cannot be solved at the same level of thinking we were at when we created them

    Cannot Ping ASA from 7204

    Your interface Ethernet0/0 has an inbound rule (101) that is nonexistent and I'm not sure if that means a default deny any any is applied The outbound rule (102) has a strange deny... access-list 102 deny ip 0.0.0.0 255.0.0.0 any I believe that is saying a source network of anything in the...

    3Com 5500G-EI [WOL / broadcast over subnets]

    Could do with seening your config file and a diagram if possible... I would have expected you to have multiple VLAN interfaces rather than the one and clearly broadcast traffic does not, by default, get propagated across subnets. -Blue The significant problems we face cannot be solved at the...

    3Com 5500G-EI [WOL / broadcast over subnets]

    I suspect you need helpers on the vlan interfaces... interface Vlan-interface2 udp-helper server x.x.x.x -Blue The significant problems we face cannot be solved at the same level of thinking we were at when we created them

    5500G EI ACL or source based routing

    I don't believe you can with that device as Policy Based Routing is not supported on the 5500 range. The reason is that it is not possible to achieve wire speed routing using PBR, something that 3Com do not want to compromise on a switch. The alternative is to use a lollipop router (such as a...

    disable l3 switching???

    The switch will route automatically if you have VLANs defined with interfaces that have an IP address, so assuming you have no VLAN interfaces defined it will not route. Remove any qos statements from the port interfaces. -Blue The significant problems we face cannot be solved at the same...

    Implementing VLANs - going from class B to C on local LAN

    OK once more... Yes you can. Your router will have a /24 interface on the 10.1.1.1 network but a /16 route on it for the 10.1.0.0 network via your L3 device. Your L3 should have interfaces to all the 10.1.x.0/24 networks so does not need routes defining - as it has connected interfaces...

    Implementing VLANs - going from class B to C on local LAN

    No problem... I was assuming there was some logical separation but you're obviously just using the ranges for convinience only... As stated by everyone, what you are proposing is quite standard, and straightforward to setup. So the answer is still yes! -Blue The significant problems we face...

    Implementing VLANs - going from class B to C on local LAN

    Aren't they /24 ranges rather than /16... 10.1.2.x/16 is in fact 10.1.x.x/16 10.1.2.x/24 is 10.1.2.0 to 10.1.2.255 Essentially each site is a single /16 range split into a number of /24 subnets (VLANS). For each subnet you require you will need a VLAN interface (address) on your L3 device...

    3 com switch

    It should work for all the switches as there is no way to disable the recover facility... "The password recovery feature allows you to reset the admin user password by logging into the unit via the console port using the username recover and password recover. If you power cycle the unit within...

    3Com Link Aggregation

    No, one of the benefits of XRN is to allow you to remove a single point of failure from the infrastructure, so rather than having an aggregation link back to one device you spread the links across two. Interestingly, 3Com engineers do NOT recommend using LACP, preferring to manually create the...

    VLAN 1 not talking between 4050 and 5500G-EI

    Is it a /24 network or two smaller networks that you are trying to link together? -Blue The significant problems we face cannot be solved at the same level of thinking we were at when we created them

    Basic understanding of 3com 4900

    The 4900 is an early L3 device so not particularly sophisticated, but L3 none the less... So, if you add an IP address to each of the VLAN interfaces the switch will automatically route between the VLANS. -Blue The significant problems we face cannot be solved at the same level of thinking we...

    3com 5500 10GB link slower than 1GB Uplink

    It should be on by default... The command is "jumboframe enable" and to turn it off is "undo jumboframe enable". This should be run from the interface context.. interface TenGigabitEthernet1/1/1 jumboframe enable To confirm run the "display interface TenGigabitEthernet1/1/1", part of the...

    Backing up an ASA

    I believe this relates to WHERE the TFTP traffic is being generated on the ASA and if the traffic is being recognised as interesting and thus sent down the tunnel. The TFTP traffic never passes THROUGH an interface so is not identified as interesting, and thus sent down the tunnel. You'll have...

    3com 5500 10GB link slower than 1GB Uplink

    Normally jdoebling would be correct, however there's a known issue with frame size and the 10Gb modules.. . We had to enable jumbo frames at both ends in order to get them working correctly! In most instances Jumbo frames are not encountered even when such things as 802.1p and/or Q in Q...

    default VLAN question

    Yes, there always has to be at least one VLAN, also by default VLAN 1 is used for the management interface, which is why you cannot delete it. -Blue The significant problems we face cannot be solved at the same level of thinking we were at when we created them
