F0615-O
Warning: Traffic mirrored to a VLAN may contain control traffic. This may be interpreted by the
downstream neighbor as legal control frames. Users should disable any protocols on inter-switch
connections that might be affected (for example, Spanning Tree).
Routing
You cannot overwrite the IP address of a configured interface if the new IP address is in the same
subnet as the original. You must first delete the existing interface IP address and then add the new IP
address.
The C5 will not add a dynamic host route to its routing table for a subnet it already knows about.
The C5 does not support configuring the host‟s gateway to be a local routed interface IP. The host‟s
gateway must exist on a different device in the network, if one is configured.
The C5 only supports one default route. If a default route is configured on the router, it will take
precedence over the default route configured for the host IP.
ACLs
You can apply an ACL to a routed VLAN interface or a policy to a port. However, the device does not
support enabling both features simultaneously on a port that is part of a routed VLAN interface.
IPv6
14036 When using IPv6 management, the movement of the master as the result of a “set switch
movemanagement” commands or a reset, can result in the loss of the host address. This can result in
the loss of remote management. This can only be recovered by reloading the configuration.
Servers for RADIUS, Syslog, PWA, or SNTP cannot be configured with an IPv6 address.
OSPFv3 virtual links are not displayed in the OSPF adjacency table.
RIP
If a secondary address is added to an interface advertising RIPv2 via the “redistribute connect”
command, the router will send an initial RIP response packet which includes the secondary address.
But in subsequent updates, the route is not advertised.
RIP stops calculating cost properly if cost ever equaled 16. If route cost is reduced below 16, the cost
will not be propagated downstream properly.
14132 RIP md5 authentication has an invalid format.
Workaround: Do not use md5 authentication for RIP.
OSPFv2
OSPF area 0 is always configured by default on the C5.
The OSPF ABR doesn‟t insert the default route into the NSSA when using the command “area
<area_id> nssa”. The default does get inserted when using the command “area <area_id> nssa
default-information-originate”.
The C5 only redistributes inter-area and intra-area OSPF routes via RIP. The redistribution of external
type 1, external type 2, NSSA, and stub routes into RIP is not supported.
Area default-cost parameter isn‟t used when the ABR router is configured for an NSSA.
The C5 does not redistribute the default route via OSPF redistribution.
When creating a stub or NSSA area, in order to remove the existing summary or external LSAs before
they age out naturally, all of the stub/NSSA area routers can either be reset, or the user can stop and
restart the OSPF process. Otherwise, after 3600 seconds have passed, the MaxAged Summary or
External LSAs will be removed automatically.
Multicast Routing
The output of “show ip mroute” will display the source mask address as 0.0.0.0.
The mroute table source network field displays the host IP address, not the host network.
